Sep 24, 2026In the Linux kernel, the following vulnerability has been resolved: usbip: vhci_hcd: fix NULL deref in status_show_vhci platform_get_drvdata() can return NULLCVE-2026-97484 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67
In the Linux kernel, the following vulnerability has been resolved: usbip: vhci_hcd: fix NULL deref in status_show_vhci platform_get_drvdata() can return NULL if a VHCI host controller's probe failed (e.g. due to USB bus number exhaustion). status_show_vhci() checked for a NULL pdev but not for a NULL hcd returned by platform_get_drvdata(). Passing NULL to hcd_to_vhci_hcd() does not return NULL - it returns a pointer offset of 0x260, causing a NULL pointer dereference when that value is subsequently dereferenced. Add a NULL check on hcd before calling hcd_to_vhci_hcd(). Move status_show_not_ready() above status_show_vhci() to make it callable from the new error path without a forward declaration.

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: validate assoc response length before status and IE access cfg80211_rx_assoc_resp() initialises the status and response-IE fields of cfg80211_connect_resp_params from the management frame before proving that the frame is long enough for those offsets. S1G and regular association responses also have different IE offsets, but the S1G path only patched resp_ie after the unsafe initialiser had already run. Defer resp_ie, resp_ie_len, and status to after the link-iteration loop. Use a bool to remember whether the frame is S1G, then validate the appropriate minimum length and set all three fields in a single if/else block. Funnel short-frame and SME-reject cleanup through a shared free_bss label for the abandon paths.

Sep 24, 2026In the Linux kernel, the following vulnerability has been resolved: nfsd: add missing read barrier to rpc_status_get dumpit seqcount retry The hand-rolled seqCVE-2026-93229 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67High 7.1
In the Linux kernel, the following vulnerability has been resolved: nfsd: add missing read barrier to rpc_status_get dumpit seqcount retry The hand-rolled seqcount-like protocol in nfsd_nl_rpc_status_get_dumpit() is missing a read memory barrier (smp_rmb) before its second counter check. The standard kernel read_seqcount_retry() includes smp_rmb() to ensure that all data reads complete before the counter is re-checked. Without this barrier, on weakly-ordered architectures (ARM, POWER), the CPU may reorder field reads past the second counter check, making the retry logic ineffective: it could observe a consistent counter pair while reading fields that have been concurrently modified by the writer. Add smp_rmb() before the second counter check to order the field reads ahead of it, matching the barrier semantics of the standard seqcount read-side. The begin-side smp_load_acquire() already pairs with the smp_store_release() in nfsd_dispatch(); with the smp_rmb() now ordering the field reads, the retry check no longer needs acquire semantics and reads the counter with a plain READ_ONCE(), as read_seqcount_retry() does. [ cel: Use READ_ONCE instead of smp_load_acquire() ]

A flaw was found in Netty's Online Certificate Status Protocol (OCSP) Client. The client fails to verify the 'id-kp-OCSPSigning' Extended Key Usage (EKU) in OCSP responder certificates. A remote attacker, holding any valid certificate issued by the same Certificate Authority (CA), can exploit this by forging 'GOOD' OCSP responses for revoked certificates. This bypasses certificate revocation checks, allowing applications using Netty's OCSP Client to accept certificates that should have been revoked, leading to an authorization bypass.

Sep 17, 2026In the Linux kernel, the following vulnerability has been resolved: liveupdate: Remember FLB retrieve() status LUO keeps track of successful retrieve attemptsCVE-2026-92483 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67
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: nvmet: fix return status of RMI log page on allocation failure nvmet_execute_get_log_page_rmi() leaves 'status' holding NVME_SC_SUCCESS (set by the successful nvmet_req_find_ns() call) when the kzalloc() for the log buffer fails. It then jumps to the out label and completes the request with a success status, so the host is told the command succeeded while no data was transferred. Initialize 'status' to NVME_SC_INTERNAL, matching the smart log handler, so an allocation failure is reported as an internal error.

In the Linux kernel, the following vulnerability has been resolved: ksmbd: scope session state changes to bound connections ksmbd_all_conn_set_status() treats every connection whose transient binding flag is set as belonging to the target SessionId. A logoff or session replacement can consequently move an unrelated connection to NEED_RECONNECT or NEED_SETUP. Pass the target session itself and select connections using either the connection-local session xarray or the session's permanent channel list. Use the same association test while waiting for requests to drain. Serialize session-wide status changes under request_lock and do not overwrite EXITING or RELEASING.

In the Linux kernel, the following vulnerability has been resolved: tpm: st33zp24: Return zero on status read failure st33zp24_status() ignores the result of the transport read and returns data even when no byte was received. The I2C transport, for example, skips i2c_master_recv() when the register-select write is short or fails, leaving data uninitialized. The resulting stack value can be interpreted as TPM_STS flags and let status checks complete spuriously. The status callback cannot propagate a transport error. Return zero unless recv() reports exactly one byte. With no status bits set, callers retry or take their existing timeout or error path instead of acting on an invalid status value.

Sep 16, 2026In the Linux kernel, the following vulnerability has been resolved: s390/vfio-ap: Fix NULL deref in status_show() during queue probe When vfio_ap_mdev_probe_qCVE-2026-89955 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67
In the Linux kernel, the following vulnerability has been resolved: s390/vfio-ap: Fix NULL deref in status_show() during queue probe When vfio_ap_mdev_probe_queue() creates the sysfs attribute group, the queue's driver data has not yet been set. A concurrent read of the 'status' attribute can therefore call dev_get_drvdata() and get NULL, which is then passed directly to vfio_ap_mdev_for_queue() where q->apqn is unconditionally dereferenced, causing a NULL pointer dereference. Fix this by acquiring the update locks before calling sysfs_create_group(). The status_show() function acquires guests_lock before reading the driver data, so any concurrent read will block until after dev_set_drvdata() has been called and the update locks are released. As a bonus, the APQN no longer needs to be read from the queue struct after allocation — it can be read directly from apdev before allocation and stored in a local variable, which is then assigned to q->apqn once the allocation succeeds.

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Reject non-SCSI SRB on status IOCB fast path qla2x00_status_entry() filters out non-TYPE_SRB entries and the SRB_NVME_CMD, SRB_BIDI_CMD and SRB_TM_CMD types, then falls through to a SCSI fast path that assumes the command is an SRB_SCSI_CMD. The first thing on that path, qla_chk_edif_rx_sa_delete_pending(), and the subsequent handling both evaluate GET_CMD_SP(sp), i.e. sp->u.scmd.cmd. The srb u union overlays the SCSI command pointer with other command layouts (bsg_job, iocb_cmd). If firmware delivers an unexpected STATUS_TYPE IOCB for a non-SCSI handle, sp->u.scmd.cmd can read as a non-NULL garbage pointer, bypassing the NULL checks in qla_chk_edif_rx_sa_delete_pending() and at the cp == NULL test, and leading to a wild pointer dereference. Reject any SRB whose type is not SRB_SCSI_CMD before entering the fast path. The outstanding_cmds slot is left untouched so a genuinely non-SCSI command still completes through its proper handler.

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Bound rsp_info_len to avoid OOB sense-data read In qla2x00_status_entry(), the FWI2 status path advances sense_data and shrinks par_sense_len by rsp_info_len: if (IS_FWI2_CAPABLE(ha)) { sense_data += rsp_info_len; par_sense_len -= rsp_info_len; } rsp_info_len is a 32-bit value taken directly from the target's FCP response (sf.rsp_data_len), while par_sense_len is the IOCB data area size (28 bytes for 24xx, 60 bytes for 29xx). A hostile or buggy target reporting an rsp_info_len larger than par_sense_len makes the unsigned subtraction underflow to a huge value and advances sense_data out of bounds. The underflowed par_sense_len then defeats the cap in qla2x00_handle_sense(): if (sense_len > par_sense_len) sense_len = par_sense_len; memcpy(cp->sense_buffer, sense_data, sense_len); so the memcpy reads up to SCSI_SENSE_BUFFERSIZE bytes from the out-of-bounds sense_data pointer, leaking adjacent response-ring/heap memory into the command's sense buffer. Clamp rsp_info_len to par_sense_len before the subtraction so par_sense_len can never underflow and sense_data stays within the IOCB data

Sep 11, 2026In the Linux kernel, the following vulnerability has been resolved: nfsd: restore rq_status_counter to even on all nfsd_dispatch() exit paths nfsd_dispatch() CVE-2026-89705 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67High 7.1
In the Linux kernel, the following vulnerability has been resolved: nfsd: restore rq_status_counter to even on all nfsd_dispatch() exit paths nfsd_dispatch() sets rq_status_counter to an odd value once a request has been decoded, and back to an even value once it has been fully processed, forming a seq-lock like protocol with the lockless reader in nfsd_nl_rpc_status_get_dumpit(). Only the fully successful path restored the counter to even. The cache-hit (RC_REPLY), drop (RC_DROPIT / RQ_DROPME) and encode-error paths all return after the odd-valued store without ever bringing the counter back to even. Once one of those paths is taken, rq_status_counter is left odd: the next request's decode ORs in 1 (still odd) and only a subsequent successful encode restores even. While stuck odd, the dumpit reader treats the rqstp fields as stable and its retry check compares against the same unchanging odd value, so it never detects concurrent mutation. This exposes actively mutating fields (e.g. args->ops / args->opcnt during compound decode and release) to the lockless reader, which can read past the end of the 8-element inline ops array. Add a helper that advances the counter to the next

Sep 11, 2026In the Linux kernel, the following vulnerability has been resolved: nfsd: set SC_STATUS_FREED in nfsd4_drop_revoked_stid for delegations nfsd4_drop_revoked_stCVE-2026-89703 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67Critical 9.8
In the Linux kernel, the following vulnerability has been resolved: nfsd: set SC_STATUS_FREED in nfsd4_drop_revoked_stid for delegations nfsd4_drop_revoked_stid() handles FREE_STATEID for admin-revoked delegations but does not set SC_STATUS_FREED before releasing cl_lock. revoke_delegation() uses this flag to detect whether FREE_STATEID has already processed the delegation -- without it, the freed delegation is added to cl_revoked via list_add(), producing a use-after-free when cl_revoked is later traversed in __destroy_client(). The SC_STATUS_REVOKED path in nfsd4_free_stateid() (line 7983) already sets SC_STATUS_FREED correctly. Apply the same pattern to the SC_STATUS_ADMIN_REVOKED path in nfsd4_drop_revoked_stid().

Sep 11, 2026In the Linux kernel, the following vulnerability has been resolved: nfsd: defer vfree of compound ops to fix rpc_status UAF The rpc_status netlink dumpit walkCVE-2026-89690 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67High 7.8
In the Linux kernel, the following vulnerability has been resolved: nfsd: defer vfree of compound ops to fix rpc_status UAF The rpc_status netlink dumpit walks every in-flight svc_rqst under rcu_read_lock and, for NFSv4 requests, reads opnums out of args->ops[]. But args->ops is a separate vmalloc buffer freed synchronously by vfree() in nfsd4_release_compoundargs() at the end of every compound. The dumpit's rcu_read_lock pins the svc_rqst struct itself (freed via kfree_rcu), but nothing defers the vfree of the ops buffer across the RCU grace period. A concurrent compound completion can therefore free the buffer while the dumpit is reading it — a use-after-free on vmalloc memory. The trailing seqcount recheck (smp_load_acquire of rq_status_counter) cannot undo a load that already retired against freed memory. Fix by replacing vfree(args->ops) with kvfree_rcu_mightsleep(), which defers the free until after an RCU grace period. This makes the existing rcu_read_lock in the dumpit sufficient to protect the read. The tradeoff is that completed compound ops buffers (up to 200 * sizeof(struct nfsd4_op)) persist in memory slightly longer, across one grace period, before being reclaimed

OpenAI Codex Desktop for Windows and macOS automatically inspected Git metadata and working-tree status when a user opened a workspace. If the workspace contains a repository with preserved attacker-controlled .git/config, the attr.tree setting and a configured clean or process filter can cause Git to run an attacker-controlled program. The program runs outside Codex's command sandbox with the signed-in user's privileges, without a workspace-trust prompt, command approval, or interaction with a model. The attacker can read, modify, or delete files and access credentials available to that user. Exploitation requires Git to be available on PATH and the user to open the attacker-prepared repository with its local Git configuration intact. An ordinary Git clone does not copy the source repository's .git/config and is not sufficient by itself.
