• Aug 15, 2026In the Linux kernel, the following vulnerability has been resolved: dma-buf: dma-fence: Fix potential NULL pointer dereference The commit mentioned in the fixCVE-2026-72094 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67

  In the Linux kernel, the following vulnerability has been resolved: dma-buf: dma-fence: Fix potential NULL pointer dereference The commit mentioned in the fixes tag below introduced a mechanism through which fence producers can fully decouple from fence consumers. This, desirable, mechanism is based on the fence's signaled-bit as the "decoupling point". A sophisticated interaction between RCU and atomic instructions attempts to ensure that fence consumers can still interact with fence producers through the dma_fence_ops (callback pointers into the producer). This is the desired behavior: to check for decoupling, the signaled-bit is first checked. If it's not yet signaled, RCU ensures that the ops pointer cannot yet be NULL. Hereby, dma_fence_signal_timestamp_locked() first sets the signaled-bit, and then sets the ops pointer to NULL. Readers first load the ops pointer, and then check through the signaled-bit whether the pointer can legally be accessed. These set and load operations could occur out of order on weakly ordered platforms. This problem can be solved very elegantly by using the ops pointer itself as the synchronization point. The pointer is either NULL, or cannot b

  In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix use-after-free in amdxdna_gem_dmabuf_mmap() When vm_insert_pages() fails, the error path calls vma->vm_ops->close(vma) which internally calls drm_gem_vm_close() → drm_gem_object_put(), releasing the GEM object reference acquired at the start of the function. However, the close_vma label then falls through to put_obj, which calls drm_gem_object_put() a second time on the same object. If the first put releases the last reference, the object is freed and the second put accesses freed memory, causing a use-after-free. Fix by returning directly from close_vma instead of falling through to put_obj, since the close handler already performs all necessary cleanup including the object put.

  In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: reject command submission on devices without a submit op amdxdna_cmd_submit() calls xdna->dev_info->ops->cmd_submit() unconditionally, but only aie2_dev_ops defines that callback. aie4_vf_ops (the AIE4 SR-IOV virtual function) does not, so a user AMDXDNA_EXEC_CMD ioctl on an AIE4 device reaches a NULL function-pointer call and oopses the kernel. AIE4 submits work through a mapped user queue and doorbell, not this ioctl path. Reject the submission early with -EOPNOTSUPP when the device provides no cmd_submit op, so the shared EXEC ioctl is a clean no-op on such devices.

  In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: reject user command submission without a command BO amdxdna_drm_submit_execbuf() passes the user-supplied command BO handle straight into amdxdna_cmd_submit() with drv_cmd == NULL. When the handle is AMDXDNA_INVALID_BO_HANDLE (0), the block that fetches job->cmd_bo is skipped, leaving it NULL, and no check rejects it on the user path (the !job->cmd_bo guard lives inside the != INVALID branch). The job is then armed and pushed to the DRM scheduler. aie2_sched_job_run() takes the drv_cmd == NULL path and calls amdxdna_cmd_set_state(job->cmd_bo) -> amdxdna_gem_vmap(NULL) -> to_gobj(NULL)->dev, a NULL pointer dereference in the drm_sched worker. A process with access to the accel node on a system with a probed AMD NPU can trigger a kernel oops with a single AMDXDNA_EXEC_CMD ioctl (cmd_handles = 0). Only internal driver commands (SYNC_DEBUG_BO / ATTACH_DEBUG_BO) legitimately pass AMDXDNA_INVALID_BO_HANDLE, and they always set drv_cmd. Reject the invalid handle for user submissions (drv_cmd == NULL) at the submit choke point so every user path is covered. Found by 0sec automated security-research tool

  In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Use caller client for debug BO sync amdxdna_drm_sync_bo_ioctl() looks up args->handle in the ioctl caller's drm_file. For SYNC_DIRECT_FROM_DEVICE, it then calls amdxdna_hwctx_sync_debug_bo(), but passes abo->client. amdxdna_hwctx_sync_debug_bo() uses the passed client both as the handle namespace for debug_bo_hdl and as the owner of the hardware context xarray. Those must match the file that supplied args->handle. The BO's stored client pointer is object state, not the ioctl context. Pass filp->driver_priv instead, matching the original handle lookup.

  In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Reject firmware log with size smaller than header fw_log_from_bo() validates the tracing buffer header_size and that the log fits within the BO, but never checks that log->size is at least log->header_size. fw_log_print_buffer() then computes: u32 data_size = log->size - log->header_size; which underflows to a near-U32_MAX value when firmware reports a log whose size is smaller than its header. That huge data_size defeats the log_start/log_end bounds clamps added by commit dd1311bcf0e6 ("accel/ivpu: Add bounds checks for firmware log indices"), so fw_log_print_lines() reads far past the small real data region of the BO. A size of 0 also makes fw_log_from_bo() advance the offset by 0, causing the callers to loop forever on the same header. Reject logs whose size is smaller than the header (which also rejects size == 0).

  In the Linux kernel, the following vulnerability has been resolved: scsi: xen: scsiback: Free the command tag on the TMR submit-failure path scsiback_device_action() obtains a command tag in scsiback_get_pend_req() and submits a task-management request with target_submit_tmr(). When target_submit_tmr() fails it returns < 0 and scsiback jumps to the err: label, which sends a response but frees nothing, leaking the tag. Impact: a pvSCSI guest can leak the command tags of a LUN's session, stopping the LUN, by issuing VSCSIIF_ACT_SCSI_ABORT or RESET requests whenever target_submit_tmr() fails. transport_generic_free_cmd() cannot be used here. By the time target_submit_tmr() returns an error it has already run __target_init_cmd() (so se_cmd->cmd_kref is one, not zero), and on its target_get_sess_cmd() error path it has freed se_cmd->se_tmr_req via core_tmr_release_req() while leaving SCF_SCSI_TMR_CDB set and the pointer dangling. Letting the command release run target_free_cmd_mem() would then double-free se_tmr_req. Use the same helper, which returns just the tag, on this path too.

  In the Linux kernel, the following vulnerability has been resolved: scsi: xen: scsiback: Free unsubmitted command instead of double-putting it scsiback_get_pend_req() obtains a command tag and returns a vscsibk_pend whose embedded se_cmd has only been memset to 0, so its cmd_kref is 0; the se_cmd is initialised (kref_init() via target_init_cmd()) only later, in scsiback_cmd_exec(), on the successful VSCSIIF_ACT_SCSI_CDB path. The two error paths in scsiback_do_cmd_fn() taken before the command is submitted -- a failed scsiback_gnttab_data_map() and an unknown ring_req.act -- call transport_generic_free_cmd(&pending_req->se_cmd, 0), which kref_put()s a refcount of 0. That underflows it ("refcount_t: underflow; use-after-free") and, as the release function is not run, leaks the command tag. Impact: a pvSCSI guest can leak every command tag of a LUN's session, stopping the LUN, by submitting requests with a bad grant reference or an unknown request type; under panic_on_warn the refcount underflow panics the host. Add a helper that just returns the tag with target_free_tag() and sends the error response. It frees the tag while the v2p reference still pins the session, and snapshots

  In the Linux kernel, the following vulnerability has been resolved: scsi: target: Bound PR-OUT TransportID parsing to the received buffer core_scsi3_decode_spec_i_port() and core_scsi3_emulate_register_and_move() hand the raw PERSISTENT RESERVE OUT parameter buffer to target_parse_pr_out_transport_id() without telling it how many bytes are valid. For an iSCSI TransportID (FORMAT CODE 01b), iscsi_parse_pr_out_transport_id() locates the ",i,0x" ISID separator with an unbounded strstr() (and on the error path prints the name with a further unbounded "%s"). An initiator can submit a TransportID whose iSCSI name contains neither a ",i,0x" substring nor a NUL terminator, filling the parameter list to its end, so the scan runs off the end of the buffer. When the parameter list spans more than one page the buffer is a multi-page vmap (transport_kmap_data_sg()), so the over-read walks into the trailing vmalloc guard page and oopses (KASAN: vmalloc-out-of-bounds in strstr). It is reachable by any fabric that delivers a PR OUT to a device exported through an iSCSI TPG, including a guest via vhost-scsi.

  In the Linux kernel, the following vulnerability has been resolved: scsi: target: core: Fix iSCSI ISID use-after-free in REGISTER AND MOVE core_scsi3_emulate_pro_register_and_move() maps the PERSISTENT RESERVE OUT parameter list with transport_kmap_data_sg() and parses the destination TransportID with target_parse_pr_out_transport_id(). For an iSCSI TransportID (FORMAT CODE 01b), iscsi_parse_pr_out_transport_id() returns the ISID in iport_ptr as a raw pointer into that mapped buffer. The function then unmaps the buffer with transport_kunmap_data_sg() before dereferencing iport_ptr in strcmp(), __core_scsi3_locate_pr_reg() and core_scsi3_alloc_registration(). When the parameter list spans more than one page (PARAMETER LIST LENGTH > 4096), transport_kmap_data_sg() uses vmap() and transport_kunmap_data_sg() does vunmap(), so the kernel virtual address backing iport_ptr is torn down and every subsequent dereference is a use-after-free read of the unmapped region. Keep the parameter list mapped until iport_ptr is no longer needed: drop the early transport_kunmap_data_sg() and unmap once on the success path, right before returning.

  In the Linux kernel, the following vulnerability has been resolved: scsi: elx: efct: Fix refcount leak in efct_hw_io_abort() When efct_hw_reqtag_alloc() fails in efct_hw_io_abort(), the error path returns -ENOSPC without releasing the reference obtained via kref_get_unless_zero() earlier in the function. All other error paths correctly drop the reference. This causes a permanent reference leak on the io_to_abort object. Additionally, the abort_in_progress flag is left set to true on this path, which means future abort attempts for the same I/O will immediately return -EINPROGRESS even though the abort was never submitted, effectively blocking recovery. Fix this by adding the missing kref_put() call and reset abort_in_progress to false, matching the cleanup done in the efct_hw_wq_write() failure path below.

  In the Linux kernel, the following vulnerability has been resolved: fs/resctrl: Fix use-after-free during unmount During unmount or failure teardown all mon_data structures that contain monitoring event file private data are freed after which kernfs nodes are removed. However, the RDT_DELETED flag is never set for the statically allocated default resource group. A concurrent reader of an event file associated with the default resource group may, after dropping kernfs active protection, block on rdtgroup_mutex while unmount proceeds to free the file private data and destroy the kernfs node without waiting for the reader. When the mutex is released, the reader wakes up, observes that RDT_DELETED is not set for the default group, and dereferences the already-freed file private data.

The RX datapath in mlx5e_macsec_offload_handle_rx_skb() looks up the SC under rcu_read_lock() via xa_load(), takes a reference with dst_hold() and attaches the dst to the skb with skb_dst_set(). A reader that already obtained the rx_sc pointer can race with the delete path and operate on freed memory. Fix the owner side by dropping the reference with dst_release() instead of freeing unconditionally, and convert the RX datapath to dst_hold_safe() so a reader racing the SC delete cannot attach a dst whose last reference was just dropped; only attach it when a reference was actually taken. mlx5e_macsec_add_rxsc() also published sc_xarray_element via xa_alloc() before rx_sc->md_dst was allocated and initialised, so a datapath reader that looked the SC up by fs_id could observe rx_sc with md_dst still NULL or, on weakly-ordered architectures, a non-NU

  In the Linux kernel, the following vulnerability has been resolved: tracing/user_events: Fix use-after-free in user_event_mm_dup() user_event_mm_dup() walks the parent mm's enabler list locklessly under rcu_read_lock() during fork() (from copy_process()); it does not take event_mutex: rcu_read_lock(); list_for_each_entry_rcu(enabler, &old_mm->enablers, mm_enablers_link) enabler->event = user_event_get(orig->event); user_event_enabler_destroy() removes an enabler from that list with list_del_rcu() and then, without waiting for a grace period, drops the enabler's user_event reference with user_event_put() and frees the enabler with kfree(). A reader that loaded the enabler before the list_del_rcu() can still be walking it, which leads to two use-after-frees: - kfree(enabler) frees the enabler while that reader dereferences enabler->event. - user_event_put() may drop the last reference to the user_event, which is then freed (via delayed_destroy_user_event() on a work queue), while the same reader does user_event_get(orig->event) on it.

  In the Linux kernel, the following vulnerability has been resolved: wifi: libertas_tf: fix use-after-free in lbtf_free_adapter() lbtf_free_adapter() calls timer_delete(&priv->command_timer), which does not wait for a running command_timer_fn() callback. lbtf_free_adapter() runs on the teardown path right before ieee80211_free_hw() frees priv, both in lbtf_remove_card() and in the probe error path. command_timer is armed by mod_timer() in lbtf_cmd() whenever a firmware command is sent. command_timer_fn() dereferences priv. If a command times out as the device is removed, command_timer_fn() runs concurrently with teardown and dereferences priv after it has been freed. This is the same use-after-free that commit 03cc8f90d053 ("wifi: libertas: fix use-after-free in lbs_free_adapter()") fixed in the sibling libertas driver. The libertas_tf variant has the identical pattern and was left unchanged. Use timer_delete_sync() so any in-flight callback completes before priv is freed.

  In the Linux kernel, the following vulnerability has been resolved: locking/rt: Fix the incorrect RCU protection in rt_spin_unlock() rt_spin_unlock() releases the RCU protection before unlocking the lock. That opens the door for the following UAF scenario: T1 T2 spin_lock(&p->lock); rcu_read_lock(); invalidate(p); p = rcu_dereference(ptr); rcu_assign_pointer(ptr, NULL); if (!p) return; spin_unlock(&p->lock); spin_lock(&p->lock) lock(&lock->lock); rcu_read_lock(); kfree_rcu(p); rcu_read_unlock(); .... spin_unlock(&p->lock) rcu_read_unlock(); // Ends grace period rcu_do_batch() kfree(p); UAF -> rt_mutex_cmpxchg_release(&lock->lock...) Regular spinlocks keep preemption disabled accross the unlock operation, which provides full RCU protection, but the RT substitution fails to resemble that. Same applies for the rwlock substitution. Move the rcu_read_unlock() invocation past the unlock operations to match the non-RT semantics. This makes it asymmetric vs. rt_xxx_lock(), but that's harmless as the caller needs to hold RCU read lock across the lock operation. The migrate_enable() call stays before the unlock operation because

  In the Linux kernel, the following vulnerability has been resolved: posix-cpu-timers: Use u64 multiplication in update_rlimit_cpu() update_rlimit_cpu() converts the RLIMIT_CPU value to nanoseconds with u64 nsecs = rlim_new * NSEC_PER_SEC; On 32-bit kernels both rlim_new (unsigned long) and NSEC_PER_SEC (1000000000L) are 32-bit, so the multiplication is performed in unsigned long and truncated for rlim_new > 4 seconds before being widened to u64. The same file already casts to u64 for the matching computation in check_process_timers(): u64 softns = (u64)soft * NSEC_PER_SEC; As a result, the truncated value is installed into the CPUCLOCK_PROF expiry cache (nextevt), causing the process CPU timer to be programmed to fire prematurely for any RLIMIT_CPU soft limit >= 5 seconds. The actual SIGXCPU/SIGKILL decision in check_process_timers() already casts to u64 and is therefore correct, so limit enforcement is not broken; only the expiry-cache programming is wrong. Apply the same cast here so both paths convert rlim_cur identically. 64-bit kernels are unaffected.

  In the Linux kernel, the following vulnerability has been resolved: net: mana: Sync page pool RX frags for CPU MANA allocates RX buffers from page pool fragments when frag_count is greater than 1. In that case the buffers remain DMA mapped by page pool and the RX completion path does not call dma_unmap_single(). As a result, the implicit sync-for-CPU normally performed by dma_unmap_single() is missing before the packet data is passed to the networking stack. This breaks RX on configurations which require explicit DMA syncing, for example when booted with swiotlb=force. Fix this by recording the page pool page and DMA sync offset when the RX buffer is allocated, and syncing the received packet range for CPU access before handing the RX buffer to the stack.

  In the Linux kernel, the following vulnerability has been resolved: gpio: tegra: do not call pinctrl for GPIO direction tegra_gpio_direction_input() and tegra_gpio_direction_output() already program the GPIO controller direction registers directly. The additional pinctrl_gpio_direction_input/output() calls do not add a Tegra pinctrl operation, because the Tegra pinmux ops provide GPIO request/free handling but no gpio_set_direction hook. The extra call still enters the pinctrl core and takes pctldev->mutex. Shared GPIO users can call the direction path while holding their per-line spinlock, so this otherwise redundant pinctrl direction call can sleep in an atomic context. This was found by our static analysis tool and then confirmed by manual review of tegra_gpio_probe(), the Tegra GPIO direction callbacks and the Tegra pinctrl ops. The reviewed path has a default non-sleeping struct gpio_chip while the direction callback still enters the pinctrl mutex path. A directed runtime validation kept the same non-sleeping chip registration and drove: gpio_shared_proxy_direction_output() gpiod_direction_output_raw_commit() tegra_gpio_direction_output() pinctrl_gpio_direction_o

  In the Linux kernel, the following vulnerability has been resolved: net: ethernet: ti: icssg: guard PA stat lookups icssg_ndo_get_stats64() unconditionally calls emac_get_stat_by_name() with FW PA stat names regardless of whether the PA stats block is present on the hardware. emac_get_stat_by_name() already guards the PA stats lookup with `if (emac->prueth->pa_stats)`; when that pointer is NULL the lookup falls through to netdev_err() and returns -EINVAL. Because ndo_get_stats64 is polled regularly by the networking stack this produces thousands of log entries of the form: icssg-prueth icssg1-eth end0: Invalid stats FW_RX_ERROR A secondary consequence is that the int(-EINVAL) return value is implicitly widened to a near-ULLONG_MAX unsigned value when accumulated into the __u64 fields of rtnl_link_stats64, silently corrupting the rx_errors, rx_dropped and tx_dropped counters reported by `ip -s link`.

  In the Linux kernel, the following vulnerability has been resolved: net: ixp4xx_hss: fix duplicate HDLC netdev allocation ixp4xx_hss_probe() allocates two HDLC netdevs. The first one is stored in ndev, initialized, and registered with register_hdlc_device(). The second one is stored in port->netdev and later used by the remove path for unregister_hdlc_device() and free_netdev(). This means that the registered netdev is not the same object that is unregistered and freed on remove. It also leaks the first allocation if the second alloc_hdlcdev() call fails, and the first allocation is not checked before ndev is used. Older code allocated the HDLC netdev only once and stored the same object in both the local variable and port->netdev. The buggy conversion split this into two alloc_hdlcdev() calls. A later rename changed the local variable name to ndev, but the underlying mismatch remained. Fix this by allocating the HDLC netdev only once and assigning the same object to port->netdev.

• Aug 15, 2026In the Linux kernel, the following vulnerability has been resolved: ieee802154: admin-gate legacy LLSEC dump operations In net/ieee802154/netlink.c, the legacCVE-2026-72049 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67High 7.1

  In the Linux kernel, the following vulnerability has been resolved: ieee802154: admin-gate legacy LLSEC dump operations In net/ieee802154/netlink.c, the legacy IEEE802154_NL family ops table builds the LLSEC dump entries (LLSEC_LIST_KEY, LLSEC_LIST_DEV, LLSEC_LIST_DEVKEY, LLSEC_LIST_SECLEVEL) with IEEE802154_DUMP() which sets no .flags, so generic netlink runs them ungated. The modern nl802154 family admin-gates the equivalent reads via NL802154_CMD_GET_SEC_KEY and friends with .flags = GENL_ADMIN_PERM. Any local uid that can open AF_NETLINK / NETLINK_GENERIC can resolve the "802.15.4 MAC" family and dump LLSEC_LIST_KEY on any wpan netdev that has an LLSEC key installed; the dump handler writes the raw 16-byte AES-128 key bytes (IEEE802154_ATTR_LLSEC_KEY_BYTES, copied verbatim from struct ieee802154_llsec_key.key) into the reply. Recovering the AES key compromises 802.15.4 LLSEC link confidentiality and authenticity, since LLSEC uses CCM* and the same key authenticates and encrypts frames. Impact: any local uid with no capabilities can read the raw 16-byte AES-128 LLSEC key from the kernel keytable on any wpan netdev that has an administrator-installed LLSEC key, by issuing an

• Aug 15, 2026In the Linux kernel, the following vulnerability has been resolved: ieee802154: ca8210: fix cas_ctl leak on spi_async failure ca8210_spi_transfer() allocates CVE-2026-72048 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67

  In the Linux kernel, the following vulnerability has been resolved: ieee802154: ca8210: fix cas_ctl leak on spi_async failure ca8210_spi_transfer() allocates cas_ctl with kzalloc_obj(GFP_ATOMIC) and relies entirely on the SPI completion callback ca8210_spi_transfer_complete() to free it. The spi_async() API only invokes the completion callback on successful submission. On failure it returns a negative error code without ever queuing the callback, which leaves cas_ctl and its embedded spi_message and spi_transfer orphaned. Every kfree(cas_ctl) in the driver is inside the completion callback, so there is no other reclamation path. ca8210_spi_transfer() is called from ca8210_spi_exchange(), the interrupt handler ca8210_interrupt_handler(), and from the retry path inside the completion callback itself. The exchange and interrupt handler paths loop on -EBUSY, so under sustained SPI bus contention every retry iteration leaks a fresh cas_ctl (~600 bytes per occurrence). Fix it by freeing cas_ctl on the spi_async() error path. While here, correct the misleading error string: the function calls spi_async(), not spi_sync().

• Aug 15, 2026In the Linux kernel, the following vulnerability has been resolved: ieee802154: ca8210: fix pointer truncation in kfifo on 64-bit ca8210_test_int_driver_writeCVE-2026-72047 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67

  In the Linux kernel, the following vulnerability has been resolved: ieee802154: ca8210: fix pointer truncation in kfifo on 64-bit ca8210_test_int_driver_write() and ca8210_test_int_user_read() exchange a kmalloc'd buffer pointer through a struct kfifo, but pass a literal '4' as the byte count to kfifo_in()/kfifo_out(). This is correct on 32-bit (pointer = 4 bytes), but on 64-bit only the low 4 bytes of the 8-byte pointer are written into the FIFO. The reader then reads back 4 bytes into an 8-byte local pointer variable, leaving the upper 4 bytes uninitialized stack data. The first dereference of the reconstructed pointer (fifo_buffer[1]) accesses an arbitrary kernel address and generally results in an oops. Use sizeof(fifo_buffer) so the byte count matches pointer width on every architecture. The driver has no architecture restriction in Kconfig, so any 64-bit build with CONFIG_IEEE802154_CA8210_DEBUGFS=y is exposed. Issue has been latent since the driver was added in 2017 because it is most commonly deployed on 32-bit MCUs. Found via a custom Coccinelle semantic patch hunting for short-byte kfifo I/O on byte-mode kfifos used to shuttle pointers.

  In the Linux kernel, the following vulnerability has been resolved: gve: fix header buffer corruption with header-split and HW-GRO The DQO RX datapath programs a per-buffer-queue-descriptor header_buf_addr at post time and reads the split header back at completion time. Both the post and the read currently index the header buffer by queue position rather than by the buffer's identity: - post (gve_rx_post_buffers_dqo): header_buf_addr is computed from bufq->tail - read (gve_rx_dqo): the header is read from desc_idx (the completion queue head index) This relies on the buffer-queue index and the completion-queue index being equal for the start of every packet, i.e. on the device consuming posted buffers and returning completions in the exact same order. That assumption does not hold once HW-GRO is enabled with multiple flows: coalesced segments are accepted and completed in an order that may differ from the order buffers were posted, and segments from different flows may interleave. That results in two problems: 1. Wrong header slot on read. Because the read offset is derived from the completion index (desc_idx) while the device wrote the header to the address

  In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: cn10k: restrict VF LMTLINE sharing to its own PF rvu_mbox_handler_lmtst_tbl_setup() uses req->base_pcifunc as a direct index into the LMT map table to read another function's LMTLINE physical base address and copy it into the caller's own LMT map table entry. The mailbox dispatcher authenticates req->hdr.pcifunc from the IRQ source, but req->base_pcifunc is a separate payload field and is not sanitized. Reject the request with -EPERM when a VF caller's base_pcifunc is not a valid function under its own PF. is_pf_func_valid() bounds the FUNC field to the PF's configured VF count, keeping the computed index inside the caller's own slot block.
