  In the Linux kernel, the following vulnerability has been resolved: liveupdate: Remember FLB retrieve() status LUO keeps track of successful retrieve attempts on an FLB. It does so to avoid multiple retrievals of the same FLB. Multiple retrievals cause problems because once the FLB is retrieved, the serialized data structures are likely freed and the FLB is likely in a very different state from what the code expects. All this works well when retrieve succeeds. When it fails, luo_flb_retrieve_one() returns the error immediately, without ever storing anywhere that a retrieve was attempted or what its error code was. If the user attempts to retrieve another file registered with the same FLB, LUO will attempt to call the FLB's retrieve() callback again. The retry is problematic for much of the same reasons listed above. The FLB is likely in a very different state than what the retrieve logic normally expects (e.g. some KHO pages may have already been restored and freed). There is no sane way of attempting the retrieve again. Remember the error retrieve returned and directly return it on a retry. This is done by changing the retrieved bool to a retrieve_status integer. A value of

  In the Linux kernel, the following vulnerability has been resolved: pinctrl: mediatek: use devm_gpiochip_add_data() for GPIO chip The gpio_chip is allocated with device-managed memory but registered with the non-managed gpiochip_add_data(). This was harmless while the drivers were built-in, but once they can be built as modules and unbound/rmmod'd, devm frees the gpio_chip's memory while it is still registered, causing a use-after-free. Register it with devm_gpiochip_add_data() so it shares the same device-managed lifecycle, which also lets the manual gpiochip_remove() error paths go away.

  In the Linux kernel, the following vulnerability has been resolved: pinctrl: mediatek: free EINT resources on unbind mtk_eint_do_init() creates an IRQ domain, populates it with a mapping for every EINT line and installs a chained handler on the parent interrupt, but none of these are ever released. This was harmless while the drivers were built-in, but now that they can be built as modules and unbound/rmmod'd it leaves behind a dangling IRQ domain, interrupt mappings whose chip data points at freed memory, and a chained handler that keeps firing into that freed data. The plain allocations in mtk_eint_do_init() already use the device-managed devm_*() helpers, so tear the remaining resources down the same way: register a devm action that detaches the chained handler, waits for any in-flight handler to finish, disposes of the per-line mappings and removes the IRQ domain. This mirrors the device-managed lifecycle adopted for the GPIO chip and keeps the whole EINT setup self-cleaning on unbind.

  In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Validate string descriptors The string descriptor length includes a two-byte header while the UTF-16 payload starts after it. utf16s_to_utf8s() expects a count of UTF-16 code units, not bytes. Passing the payload byte count can make it read beyond the descriptor buffer. Validate that the payload has an even byte count, pass a code-unit count to the converter, and allocate sufficient UTF-8 output space. The raw string buffer starts after the descriptor header but its size is bLength. Copying bLength bytes from that pointer can read beyond the response buffer. Allocate a zeroed bLength-sized buffer and copy only the UTF-16 payload. This preserves the raw buffer size consumed by the RPMB device-ID ABI while avoiding the overread.

  In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix integer overflow of user QP buffer size set_user_buf_size() computes the QP buffer size by left-shifting the user-supplied rq.wqe_cnt and rq.wqe_shift values as signed integers. A sufficiently large rq.wqe_cnt causes signed integer overflow, which is undefined behavior, and yields a small or negative buf_size, causing ib_umem_get() to map a buffer smaller than the hardware will actually write into. Replace the shifts and addition with check_shl_overflow() and check_add_overflow(), rejecting invalid user inputs. Moreover, guard the identical shift computing qp->sq.offset in _create_user_qp() before set_user_buf_size() is reached.

  In the Linux kernel, the following vulnerability has been resolved: spi: oc-tiny: switch to managed controller allocation The controller is allocated with the non-managed spi_alloc_host() while the interrupt is registered with devm_request_irq(). During removal, spi_bitbang_stop() only unregisters the controller; the subsequent spi_controller_put() then frees the controller together with its embedded driver-private devdata, which is the IRQ handler's dev_id. The devm_request_irq() release action (free_irq()), which drains the handler, does not run until after .remove() returns. A late or latched interrupt can therefore reach tiny_spi_irq() and dereference already-freed memory (e.g. hw->base). Switch to devm_spi_alloc_host() so that the devres LIFO order releases the controller only after free_irq() has drained the handler, and drop the now-redundant spi_controller_put() from .remove(). The probe error path is simplified to direct returns. This issue was found by an in-house static analysis tool.

  In the Linux kernel, the following vulnerability has been resolved: sched_ext: Abort directly from the hardlockup handler scx_hardlockup() defers the abort to an irq_work because exit claiming used to take scx_sched_lock and couldn't run from NMI. The deferral is now unnecessary - claiming is NMI-safe and asserting ->aborting is exactly what breaks the live-locks that hard-lock CPUs. Call handle_lockup() directly and drop the irq_work. This also makes the self-detected case recoverable: the perf watchdog fires on the hard-locked CPU itself, where a queued irq_work never runs with IRQs off. Also fix the return value: %true used to be returned whenever sched_ext was loaded, suppressing the kernel's hardlockup report even when the abort was refused. Return %true only when this call initiated the abort.

  In the Linux kernel, the following vulnerability has been resolved: remoteproc: Prevent crash handling to race with rproc_del() There's no synchronization between rproc_crash_handler_work() and rproc_del(), as such it's possible for a driver to be removed while crash-handler work is scheduled, or even executing - resulting in use-after-free issues. To avoid this the scheduled work need to be cancelled and synchronized against before the removal proceeds. In order to ensure that this doesn't race with the reporting, and thereby scheduling new work, a "deleting" flag is introduced. This is similar to the RPROC_DELETE state that was introduced to ensure that "start" didn't race with rproc_del(), but the existing mechanism can not be used as it's valid to call rproc_report_crash() in atomic context - and the "state" is protected by a mutex. In the event that work is cancelled the pm_stay_awake() is left unbalanced and need to be unrolled. The blocking and cancelling of crash-handler work prior to the actual rproc_shutdown() call does have the explicit side-effect that crashes resulting from the shutdown process will not enter the crash-handling path, and as such will not generate

  In the Linux kernel, the following vulnerability has been resolved: iommu/tegra241-cmdqv: Publish an LVCMDQ only after it is fully initialized tegra241_vintf_init_lvcmdq() stores the freshly allocated vcmdq pointer to the vintf->lvcmdqs[] array, before tegra241_vcmdq_alloc_smmu_cmdq() builds the vcmdq->cmdq. The error ISR dereferences that cmdq, so a latched LVCMDQ error (e.g. one inherited across a kexec) firing in this window would make tegra241_vintf0_handle_error() pass the still-zeroed arm_smmu_cmdq down to __arm_smmu_cmdq_skip_err(), dereferencing NULL queue register pointers. Drop the store from tegra241_vintf_init_lvcmdq() and publish the vcmdq at the end of the allocation instead, with an smp_store_release() that pairs with an smp_load_acquire() in the ISR, which can see a fully built LVCMDQ or NULL. The user-owned LVCMDQ allocation moves accordingly, publishing the vcmdq once tegra241_vcmdq_hw_init_user() succeeds, using a plain store since a user VINTF's lvcmdqs[] has no lockless reader -- the error ISR only walks the VINTF0 array.

  In the Linux kernel, the following vulnerability has been resolved: iommu/tegra241-cmdqv: Synchronize the error ISR against VINTF (de)init A user VINTF is torn down by tegra241_cmdqv_deinit_vintf(), which runs from the destroy callback and from the init-failure unwind in the alloc handler. It clears the cmdqv->vintfs[] slot and lets the iommufd core free it, but nothing serializes that against the error interrupt: tegra241_cmdqv_isr() reads cmdqv->vintfs[idx] and dereferences the vintf. A concurrent error can make the ISR read a slot mid-clear (a NULL deref) or use a vintf which is about to be freed (a use-after-free). deinit_vintf() also returns idx to the IDA before clearing the slot, so a concurrent create that reuses idx can publish its new vintf into the slot, only for this teardown to erase it again with the stale NULL store. On the other end, tegra241_cmdqv_init_vintf() publishes a new vintf with a plain store to the cmdqv->vintfs[] slot, and the ISR dereferences fields of a published vintf such as vintf->base. A plain store gives no ordering on a weakly-ordered CPU, and a stale VINTF_ERR_MAP bit on a reused idx can make the ISR pick a vintf the moment it is published, b

  In the Linux kernel, the following vulnerability has been resolved: iommu/tegra241-cmdqv: Free the error IRQ before tearing down VINTFs tegra241_cmdqv_remove() tears each VINTF down first, then calls free_irq(). Tearing a VINTF down frees vintf0 and clears cmdqv->vintfs[0]. An error in that window makes tegra241_cmdqv_isr() read the stale slot and hand it to tegra241_vintf0_handle_error(), which dereferences a NULL or freed pointer. Free the IRQ before tearing the VINTFs down. free_irq() waits for in-flight handlers to finish and blocks new ones, so no ISR can observe a VINTF as it is torn down. Note: a user-owned VINTF (viommu) could outlive this teardown, which unmaps cmdqv->base and frees cmdqv->vintfs, so a later viommu close then touches freed memory. This is neither introduced nor fixed here: a physical IOMMU is not a pluggable device, so iommufd by design holds no reference on the one behind a viommu, and this teardown is not expected while that viommu is still alive.

  In the Linux kernel, the following vulnerability has been resolved: iommu/tegra241-cmdqv: Fix VINTF0 leak on the init-failure path tegra241_cmdqv_init_structures() allocates VINTF0 with kzalloc_obj(), inits it, and preallocates its logical VCMDQs. Two of its error paths leak. When tegra241_cmdqv_init_vintf() fails it returns before VINTF0 reaches the cmdqv->vintfs[] array, so the devres unwind on probe failure cannot reach it; free it directly there. A later VCMDQ preallocation failure instead leaves VINTF0 published, and so this time the unwind does reach tegra241_cmdqv_remove_vintf(), which then frees it from vintf->hyp_own. But tegra241_vintf_hw_init() sets that flag only afterward, from a HW read-back, so the still-uninited VINTF0 reads as guest-owned and leaks, with mutex_destroy() and ida_destroy() run on fields it never set up. Decide ownership from vintf->idx instead, the index assigned when its id is allocated: idx 0 is the kernel-owned VINTF0, while idx >= 1 marks a guest VINTF. So the in-kernel free decision in tegra241_cmdqv_remove_vintf() and tegra241_vintf_free_lvcmdq() now keys on idx too, and hyp_own stays a pure HW-readback state.

  In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix UAF in ODP init error-handling path rxe_odp_mr_init_user() stores &umem_odp->umem in mr->umem before calling rxe_odp_init_pages(). If rxe_odp_init_pages() fails, rxe_odp_mr_init_user() releases umem_odp and returns an error. rxe_reg_user_mr() then unwinds the error through rxe_cleanup(), rxe_mr_cleanup(), ib_umem_release(mr->umem). There is an IS_ERR_OR_NULL(umem) check at the start of ib_umem_release(). But since mr->umem is NOT reset to NULL in the error handling path of rxe_odp_mr_init_user(), the check passes and it reads already-freed fields like umem->is_dmabuf, causing UAF. Fix the UAF by clearing mr->umem after releasing the failed ODP umem so the MR cleanup path does not release it again.

  In the Linux kernel, the following vulnerability has been resolved: clk: mediatek: pllfh: Fix IO remapping leak in register_pllfhs error path When mtk_clk_register_pllfhs function fails to register a PLL, it unregisters all PLLs and cleans up itself in its error path before returning, so the function callers don't need to do it. But contrary to mtk_clk_unregister_pllfhs function, that does almost the same sequence, it does not free the IO memory mapped on fhctl node, leading to a leak. Fix this leak by factorizing the cleanup sequence in a new private function and use it both mtk_clk_register_pllfhs and mtk_clk_unregister_pllfhs functions. Also, change the loop index start value to avoid the -1 operation on index at each loop.

  In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix infinite loop in nilfs_clean_segments() syzbot reported a hung task in nilfs_transaction_begin(). This occurs because the cleaner ioctl falls into an infinite loop if nilfs_segctor_construct() repeatedly returns -EROFS (e.g. the device is remounted as read-only after an I/O error). Currently in nilfs_clean_segments(), if err is non-zero, it logs the error and sleeps but doesn't abort when it encounters a terminal error like -EROFS. This causes the thread to loop forever. Fix this by breaking out of the loop if nilfs_segctor_construct() returns -EROFS. This matches the behaviour in nilfs_segctor_write_out(), which also handles -EROFS.

  In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix BUG in nilfs_copy_dirty_pages() on dirty state mismatch Syzbot reported a kernel BUG triggered within nilfs_copy_dirty_pages(), which copies dirty DAT file folios/pages to its shadow page cache. The BUG occurs when a retrieved dirty folio/page unexpectedly loses its 'dirty' status. This issue arises because, since the commit referenced below, the 'dirty' flag of a folio/page can be cleared asynchronously after the filesystem detects metadata corruption and transitions to read-only mode. Resolve the issue by returning an -EROFS error if the filesystem has transitioned to read-only mode. Also change the behavior to issue a kernel warning only once instead of triggering a kernel BUG when this unexpected 'dirty' state is detected while the filesystem is not in read-only mode.

  In the Linux kernel, the following vulnerability has been resolved: spi: davinci: switch to managed controller allocation The controller is allocated with the non-managed spi_alloc_host() while the interrupt is registered with devm_request_threaded_irq(). During removal, spi_bitbang_stop() only unregisters the controller; the subsequent spi_controller_put() then frees the controller together with its embedded davinci_spi devdata, which is the IRQ handler's dev_id. The devm_request_threaded_irq() release action (free_irq()), which drains the handler, does not run until after .remove() returns. A late or latched interrupt can therefore reach davinci_spi_irq() and dereference already-freed memory. Switch to devm_spi_alloc_host() so that the devres LIFO order releases the controller only after free_irq() has drained the handler, and drop the now-redundant spi_controller_put() from .remove(). The probe error path is simplified to direct returns. The clock is acquired with devm_clk_get_enabled(), which is registered after the IRQ and thus released before it by the devres LIFO order.

  In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Add vm_bind region with kbo range overlap check When a VM is created, caller has to specify the range of the address space carve-out set aside for mapping kernel BO's. That means vm_bind mappings of UM-exposed BO's should not intersect with that region, but at the moment we're not checking this. At first, I thought of giving these values to drm_gpuvm_init() through its reserve_{offset, range} arguments, but it turns out that is meant for VM address spans that are not managed through the usual drm_gpuvm split/merge circuit, so storing the end of the user VA range at VM creation time and doing a quick check in the vm_bind ioctl path was the simplest workaround. The new check also makes sure vm_bind range doesn't overflow the size of a 64-bit unsigned integer. That was already being done further down the call stack inside drm_gpuvm_sm_map -> drm_gpuvm_range_valid, but it's best to fail early in the driver before GPUVM functions are invoked so that we won't waste time allocating vm_bind context resources.

  In the Linux kernel, the following vulnerability has been resolved: bus: mhi: host: Fix controller cleanup on EDL sysfs failure mhi_register_controller() adds the controller device before creating the optional trigger_edl sysfs file. If sysfs_create_file() fails, the error path only drops the device reference and leaves the device registered. Hence, call device_del() in the error path before put_device().

• Sep 17, 2026In the Linux kernel, the following vulnerability has been resolved: md: remove REQ_NOWAIT support from raid1/10/456 REQ_NOWAIT support in md personalities thaCVE-2026-90401 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67High 7.1

  In the Linux kernel, the following vulnerability has been resolved: md: remove REQ_NOWAIT support from raid1/10/456 REQ_NOWAIT support in md personalities that can block internally is fundamentally incomplete. While reads can avoid some blocking paths, write requests can still encounter cases where one mirror succeeds while another returns -EAGAIN. At that point md cannot distinguish queue pressure from a real device failure, so it can neither record a bad block nor safely retry the write without REQ_NOWAIT, leaving mirrors with divergent data. Rather than continue advertising REQ_NOWAIT support for personalities that cannot implement it correctly, remove it from raid1, raid10 and raid456. Keep REQ_NOWAIT for linear and raid0, which only remap bios to their underlying devices; stacked limits will still clear the feature if any component device lacks REQ_NOWAIT support.

• Sep 17, 2026In the Linux kernel, the following vulnerability has been resolved: md: recheck spare changes before starting sync remove_spares() and remove_and_add_spares()CVE-2026-90400 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67

  In the Linux kernel, the following vulnerability has been resolved: md: recheck spare changes before starting sync remove_spares() and remove_and_add_spares() modify the array's rdev configuration. These operations are only safe after the array has been suspended. md_start_sync() checks whether spare configuration changes are needed before taking reconfig_mutex. However, the rdev state can change before the mutex is acquired, so the initial check can become stale. In that case, md_choose_sync_action() may remove or replace rdevs while normal I/O is still accessing them. The race can occur as follows: raid10d Worker Normal IO ____________ _______________________ ______________________ raid10_write_request() wait_blocked_dev() set Blocked set Faulty Skip Faulty rdev rrdev->nr_pending++ .repl_bio = bio removeable_rdev = false . array not suspended . lock mddev

  In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix stride mismatch in mac_phy_caps_parse() Currently, in ath12k_wmi_mac_phy_caps_parse(), kzalloc() sizes the mac_phy_caps buffer as tot_phy_id * len, where len is clamped to min(firmware_len, sizeof(struct ath12k_wmi_mac_phy_caps_params)). The subsequent memcpy() destination advances by sizeof(full struct) per slot via C pointer arithmetic, not by the clamped len. When firmware sends short TLVs, the second and later slots are written past the end of the allocation. The reader in ath12k_pull_mac_phy_cap_svc_ready_ext() also indexes the buffer with full-struct pointer arithmetic, so the allocation must match that stride. Fix by using kzalloc_objs(), which derives the element size from the pointer type, making allocation size and pointer stride provably consistent regardless of what len the firmware provides.

• Sep 17, 2026In the Linux kernel, the following vulnerability has been resolved: firmware: qcom: scm: Fix NULL dereference in IRQ handler before __scm is published In qcomCVE-2026-90397 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67

  In the Linux kernel, the following vulnerability has been resolved: firmware: qcom: scm: Fix NULL dereference in IRQ handler before __scm is published In qcom_scm_probe(), devm_request_threaded_irq() is called before smp_store_release(&__scm, scm). Two paths can dereference __scm before it is published, both causing a NULL pointer dereference. The IRQ handler receives scm via its data argument but passes only wq_ctx to qcom_scm_waitq_wakeup() and qcom_scm_get_completion(), which then dereference __scm directly. Thread scm through both functions so the IRQ handler path never touches __scm. Non-atomic SMC calls made during probe (e.g. from qcom_tzmem_init via qcom_scm_shm_bridge_enable) can return WAITQ_SLEEP, causing qcom_scm_wait_for_wq_completion() to run before __scm is published and dereference it. Add platform_set_drvdata(pdev, scm) early in probe and change qcom_scm_wait_for_wq_completion() to take the device pointer and use dev_get_drvdata() to reach scm, removing any dependency on __scm.
