| CVE-2026-90268 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 8.1 High |
| In the Linux kernel, the following vulnerability has been resolved: scsi: sd: Fix error handling in sd_probe() after large pool creation failure After device_add(&sdkp->disk_dev) succeeds, sd_large_pool_create() failure must unregister disk_dev and let scsi_disk_release() free sdkp. Going through out_free_index kfree()s an already registered device and leaks the sysfs entry. | ||||
| CVE-2026-90305 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ARM: 9483/1: select HAVE_POSIX_CPU_TIMERS_TASK_WORK Commit c6e61c06d606 ("ARM: 9463/1: Allow to enable RT") enabled PREEMPT_RT on ARM but did not select HAVE_POSIX_CPU_TIMERS_TASK_WORK. This leaves CONFIG_POSIX_CPU_TIMERS_TASK_WORK disabled, so CPU timers expire in hard IRQ context. On PREEMPT_RT this makes run_posix_cpu_timers() take the sleeping sighand->siglock: BUG: sleeping function called from invalid context at spinlock_rt.c:48 rt_spin_lock from lock_task_sighand lock_task_sighand from run_posix_cpu_timers run_posix_cpu_timers from update_process_times ARM handles TIF_NOTIFY_RESUME on all return-to-user paths, including v7-M. ARM32 KVM host support was removed by commit 541ad0150ca4 ("arm: Remove 32bit KVM host support"), so the select need not be conditional on KVM. Select it to defer POSIX CPU timer expiry to task context. Reproduced with setrlimit(RLIMIT_CPU, ...) and a busy loop. The same path is used by setitimer(ITIMER_PROF or ITIMER_VIRTUAL) and POSIX CPU timers created with timer_create(). | ||||
| CVE-2026-90307 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/srp: fix heap information leak on a truncated SRP_CRED_REQ srp_recv_done() passes wc->byte_len to srp_process_rsp(). It passes nothing to srp_process_cred_req() and srp_process_aer_req(), which read fixed-size fields from the receive buffer without checking that those fields were received. The buffer size is max_ti_iu_len, which comes from the login response and is not validated. A target that advertises 8 and then sends an 8-byte SRP_CRED_REQ makes the initiator read req->tag from beyond the end of the buffer. req->tag is copied into the SRP_CRED_RSP and sent back, so those bytes reach the target. SRP_AER_REQ behaves the same way and also reads req->lun. The leak is 8 bytes per response. max_ti_iu_len also decides which slab cache the buffer comes from. With 8 the buffer is a kmalloc-8 object and the read is entirely outside it: BUG: KASAN: slab-out-of-bounds in srp_recv_done+0x172b/0x1aa0 Read of size 8 at addr ffff888104714da8 by task kworker/u8:3/50 which belongs to the cache kmalloc-8 of size 8 The buggy address is located 0 bytes to the right of allocated 8-byte region [ffff888104714da0, ffff888104714da8) Without KASAN the returned bytes are whatever is next in the slab. One run returned ".strtab". rsp->data[3] in srp_process_rsp() has the same problem: only resp_data_len is checked before it is read. Drop a request that is shorter than the structure being parsed, and check byte_len before the tsk_mgmt read. | ||||
| CVE-2026-90317 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Invalidate RCU pointers after final spin unlock In a sleepable BPF program, a spin lock can provide the only RCU protection for a kptr. The final bpf_spin_unlock() ends that protection, but the verifier leaves the pointer valid. Another CPU can then free the object before the pointer is used. A capability-limited runtime PoC triggered a task_struct use-after-free in __bpf_get_task_stack(). Record whether the program is in an RCU-protected context before releasing the lock. Invalidate RCU-protected pointers only when the unlock leaves the final such context. This preserves valid pointers in non-sleepable programs and inside an explicit RCU read-side section. | ||||
| CVE-2026-90320 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ocfs2: validate external xattr entries when reading metadata ocfs2_validate_xattr_block() checks the xattr block header before the block reaches higher-level xattr users, but it does not verify that a non-indexed block's xh_count and entry offsets fit inside the block. Indexed buckets likewise reach list/get consumers after ECC without an entry-bounds check. Use the flat xattr entry validator for non-indexed external xattr blocks, and use a bucket-specific validator for indexed buckets at metadata read time. The bucket validator keeps the entry array bounded by the first bucket block while checking name/value offsets against the bucket block they target. Reject corrupted external xattr metadata before listxattr() or getxattr() can walk out-of-range entry arrays or name/value offsets. Validation reproduced this kernel report: BUG: KASAN: use-after-free in ocfs2_xattr_list_entries+0xd7/0x190 Read of size 1 at addr ffff88810a654007 by task ocfs2_xattr_lis/630 Call Trace: dump_stack_lvl+0x66/0xa0 print_report+0xce/0x630 kasan_report+0xe0/0x110 ocfs2_xattr_list_entries+0xd7/0x190 ocfs2_listxattr+0x3f6/0x610 listxattr+0x90/0xe0 path_listxattrat+0xed/0x220 do_syscall_64+0x115/0x6a0 entry_SYSCALL_64_after_hwframe+0x77/0x7f | ||||
| CVE-2026-90323 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ublk: validate auto buf reg before taking uring_cmd With UBLK_F_AUTO_BUF_REG, invalid sqe->addr can fail after ublk_fill_io_cmd() has set UBLK_IO_FLAG_ACTIVE. The uring_cmd is completed while the tag stays active, which can hang teardown. Split validation from buffer apply so the check has no side effects, then take the uring_cmd and store the already-validated buffer. Apply the same order in FETCH so io->buf is not written before __ublk_fetch() state checks. | ||||
| CVE-2026-76757 | 1 Drupal | 1 Gammu Sms Daemon | 2026-09-19 | 5.9 Medium |

| CVE-2026-90266 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: btrfs: zoned: don't force read-only on transient -EAGAIN from reloc merge On a zoned FS, btrfs_delayed_refs_rsv_refill() returns -EAGAIN whenever the over-committed metadata plus the zone_unusable bytes exceeds the usable size in a metadata block-group to avoid heavy over-commit of metadata and early ENOSPC in one transaction. If this happens while doing reclaim, the transaction is getting aborted. Treat -EAGAIN as a soft, retryable condition in case of block-group reclaim. | ||||
| CVE-2026-90273 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: coresight: etm4x: missing cscfg_csdev_disable_active_config() in perf enable In the perf enable path, there are missing cases where cscfg_csdev_disable_active_config() is not called: - Branch broadcast is selected but not supported by the hardware - etm4_enable_hw() fails This can lead to a leak of config_desc->active_cnt. Fix this by properly calling cscfg_csdev_disable_active_config() in these error paths. | ||||
| CVE-2026-90276 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: md/md-llbitmap: stop daemon timer rearm on destroy llbitmap_destroy() deletes pending_timer before flushing md_llbitmap_io_wq. However, daemon_work can still be queued or running after the timer has been deleted, and the daemon path can arm pending_timer again when it finds dirty chunks that are not ready to flush yet. If that happens during teardown, pending_timer can remain armed after llbitmap is freed and later dereference freed memory. Add a BITMAP_SHUTDOWN bit to llbitmap->flags, set it before deleting the timer, and make the timer and daemon paths stop queueing or rearming work once teardown starts. Cancel daemon_work before flushing the shared workqueue so no already queued daemon instance can race with the free. Use timer_shutdown_sync() so a daemon instance that passed the shutdown check before teardown cannot rearm the timer afterward. BITMAP_SHUTDOWN is a runtime-only state. Mask it out when reading and updating the llbitmap superblock so the shutdown state is never loaded from disk or persisted to disk. | ||||
| CVE-2026-90329 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: HID: synchronize input before cleaning up a failed probe hid_device_io_start() allows reports to run concurrently with probe. If the probe subsequently fails, __hid_device_probe() releases driver resources and clears hdev->driver without first excluding those report callbacks. For example, a report may enter hidraw_report_event() while the failure path frees the associated hidraw object, leading to a use-after-free when the report takes the object's list lock. Stop input before performing failed-probe cleanup. This reacquires driver_input_lock and waits for any report callback already in progress. | ||||
| CVE-2026-90335 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: tty: skip cdev_del() when no cdev is registered TTY device registration can fail before a cdev is allocated. Serial core keeps the port so setserial can still use it, and later removal passes the NULL cdev slot to cdev_del(), causing a NULL-pointer dereference. Only delete the cdev when the slot is not NULL. | ||||
| CVE-2026-90349 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: fix out-of-bounds link array access in mt7996_tx() When mac80211 leaves the link unspecified, mt7996_tx() substitutes the primary link id of the station or vif. That value is IEEE80211_LINK_UNSPECIFIED (0xf) until the first link has been added, and it is then used unchecked to index vif->link_conf[], mvif->mt76.link[] and sta->link[], all of which hold IEEE80211_MLD_MAX_NUM_LINKS (15) entries. Clamp the primary link id to the default link before using it, and use the clamped value for the link_sta fallback as well. | ||||
| CVE-2026-90360 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: regulator: core: use system_freezable_wq for init complete work schedule_delayed_work() uses system_wq, which is non-freezable, allowing regulator_init_complete_work to run concurrently with system suspend. This work fires ~30s after boot to disable unused regulators via I2C. When it races with PM suspend, the I2C adapter may already be suspended, triggering a -ESHUTDOWN warning in __i2c_transfer(): WARNING: ... at __i2c_transfer+0x36c/0x3c8 Call trace: __i2c_transfer i2c_transfer regmap_i2c_write _regmap_update_bits regulator_disable_regmap _regulator_do_disable regulator_late_cleanup regulator_init_complete_work_function process_one_work Switch to system_freezable_wq so the work is frozen before any device is suspended, eliminating the race. | ||||
| CVE-2026-90363 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: drm/msm: don't tear down KMS twice when KMS init fails When priv->kms_init() (mdp4_kms_init() / mdp5_kms_init()) fails partway through, both display drivers already tear their KMS state down via mdp4_destroy() / mdp5_kms_destroy() before returning the error. The common error path in msm_drm_init() then runs msm_drm_uninit() -> msm_drm_kms_uninit(), which tries to destroy the very same KMS a second time, which causes a use-after-free crash. Bring MDP4/MDP5 in line with the DPU driver whose dpu_kms_init() doesn't perform error cleanup on the failure. Let the common path own the cleanup, instead of freeing the KMS from their error paths. The crash trace for the reference: __lock_acquire from lock_acquire (kernel/locking/lockdep.c:5906 kernel/locking/lockdep.c:5863) lock_acquire from touch_wq_lockdep_map (kernel/workqueue.c:4094 (discriminator 1)) touch_wq_lockdep_map from __flush_workqueue (kernel/workqueue.c:4136) __flush_workqueue from msm_drm_kms_uninit (drivers/gpu/drm/msm/msm_kms.c:243 (discriminator 33)) msm_drm_kms_uninit from msm_drm_uninit (drivers/gpu/drm/msm/msm_drv.c:93) msm_drm_uninit from msm_drm_init (drivers/gpu/drm/msm/msm_drv.c:184) msm_drm_init from try_to_bring_up_aggregate_device (drivers/base/component.c:249 drivers/base/component.c:227) try_to_bring_up_aggregate_device from __component_add (drivers/base/component.c:269 drivers/base/component.c:748) __component_add from dsi_host_attach (drivers/gpu/drm/msm/dsi/dsi_host.c:1739) dsi_host_attach from mipi_dsi_attach (drivers/gpu/drm/drm_mipi_dsi.c:383) mipi_dsi_attach from sharp_nt_panel_probe (drivers/gpu/drm/panel/panel-sharp-ls043t1le01.c:247) Patchwork: https://patchwork.freedesktop.org/patch/742068/ | ||||
| CVE-2026-90366 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: reserve space for the CSA-abort countdown TLV When a CSA countdown is active, mt7996_mcu_beacon_cntdwn() emits two bss_bcn_cntdwn_tlv entries (the CSA countdown and the CCA-abort BCC), but MT7996_BEACON_UPDATE_SIZE only reserved one. With MBSSID enabled and a near-maximum beacon template the extra 8 bytes could push the offload command past MT7996_MAX_BSS_OFFLOAD_SIZE and trigger skb_over_panic(). Reserve room for both countdown TLVs. | ||||
| CVE-2026-90368 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: unwind state on add_interface failure When mt76_wcid_alloc() fails, mt7915_add_interface() returned without clearing the vif_mask/omac_mask bits it had already set, without removing the firmware dev info added earlier, and without clearing a monitor_vif pointer to the vif mac80211 is about to free. mac80211 does not call remove_interface() for a failed add, so the indices and firmware dev entry leaked permanently and testmode could dereference the stale monitor_vif. Add a proper error unwind. | ||||
| CVE-2026-88097 | 1 Microsoft | 1 Edge Chromium | 2026-09-19 | 8.1 High |

| CVE-2026-92483 | 1 Linux | 2 Kernel, Linux Kernel | 2026-09-19 | N/A |
| 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 0 means retrieve was never attempted, a positive value means it succeeded, and a negative value means it failed and the error code is the value. This is similar to commit f85b1c6af5bc ("liveupdate: luo_file: remember retrieve() status") which did the same for LUO files. | ||||
