10 CVE

  1. CVE-2026-97521 – Non évaluée

    Linux

    In the Linux kernel, the following vulnerability has been resolved: gfs2: fix quota init duplicate scan gfs2_quota_init() checks for duplicate quota_change IDs while holding qd_lock and the quota hash bucket bitlock. That path used gfs2_qd_search_bucket(), which takes a lockref reference via lockref_get_not_dead(). On PREEMPT_RT this may sleep, which is not allowed under the bucket bitlock, triggering "sleeping function called from invalid context". Use a no-ref bucket lookup in this path, then continue duplicate handling without taking a lockref there. Refactor gfs2_qd_search_bucket() to build on top of the no-ref helper so lookup traversal stays in one place. This patch fixes a bug reported by syzbot.

  2. CVE-2026-97520 7.1 Élevée

    Linux

    In the Linux kernel, the following vulnerability has been resolved: gfs2: move quota_init qc iterator increment Move qc++ from the loop body into the for-loop increment expression in gfs2_quota_init(). This keeps iterator progression explicit and avoids mixing pointer advance with duplicate-slot handling in the loop body.

  3. CVE-2026-97519 – Non évaluée

    Linux

    In the Linux kernel, the following vulnerability has been resolved: drm/xe: Fix null pointer dereference in devcoredump cleanup In xe_devcoredump_snapshot_free(), ss->gt may be NULL when the snapshot was never fully populated (e.g., when cleanup is triggered without a prior capture). Guard the xe_guc_capture_put_matched_nodes() call with IS_ERR_OR_NULL() to prevent a null dereference. In xe_devcoredump_free(), the deferred work is only queued when a coredump is captured, so guard cancel_work_sync() with a check on coredump->captured.

  4. CVE-2026-97514 – Non évaluée

    Linux

    In the Linux kernel, the following vulnerability has been resolved: media: chips-media: wave5: Fix Reports from Kernel Lock Validator handle_dynamic_resolution change requires that the state_lock be acquired based on the lockdep_assert_held. However, the handle_dynamic_resolution_change call in initialize_sequence does not properly obtain the lock before calling. Since the v4l2_ctrl_find and s_ctrl can sleep, they should not be called while a lock is already held. Store off the fbc_buf_count then properly update control once lock has been freed.

  5. CVE-2026-97511 – Non évaluée

    Linux

    In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: avoid out-of-bounds access in monitor In NAN, we don't know on what band the frame will be sent. Therefore we set info->band to NUM_NL80211_BANDS. However, this leads to out-of-bound access in ieee80211_add_tx_radiotap_header when we try to access the sbands array. Fix it by not accessing the array if the band is NUM_NL80211_BANDS. This means that we will not report rate info for legacy rate in NAN. But nobody really cares about it.

  6. CVE-2026-97504 – Non évaluée

    Linux

    In the Linux kernel, the following vulnerability has been resolved: watchdog: lenovo_se10_wdt: Fix use-after-free and resource leak risk Review by sashiko.dev highlighted potential use after free and resource leak instances. Set se10_pdev to null to prevent use after free Remove DMI call back and instead directly call se10_create_platform_device. Handle error cases appropriately

  7. CVE-2026-97499 – Non évaluée

    Linux

    In the Linux kernel, the following vulnerability has been resolved: coresight: perf: Retrieve path and source from event data ETM perf callbacks currently use the per-CPU csdev_src pointer, which can race with updates during device registration and unregistration. The AUX setup already builds and stores the path in the event data. Use this path to retrieve the source instead of csdev_src to avoid the race. Export coresight_get_source() and add etm_event_get_ctxt_path() to retrieve the context's path and its source with READ_ONCE() / WRITE_ONCE() accessors. Give the comments to explain why this approach is safe when pause or resume callbacks preempt the disable callback (e.g. via NMI).

  8. CVE-2026-97498 – Non évaluée

    Linux

    In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/userq: pin mqd and fw object bo to avoid eviction mqd and fw objects are queue core objects which should remain valid and never be unmapped and evicted for user queues to work properly. During eviction if these buffers are evicted the hw continue to use the invalid addresses and caused page faults and system hung.

  9. CVE-2026-97474 7.4 Élevée

    Linux

    In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mld: purge async notifications upon nic error This fixes a kernel panic in reconfig failure: 1. we have a BSS connection 2. we have a NAN connection 3. FW error occurs 4. reconfig restores the BSS connection 5. however, restoring the NAN connection fails due to a FW error. 6. erroneously, ieee80211_handle_reconfig_failure is called and marks all interfaces as not-in-driver (will be fixed in a different patch). 7. mac80211 frees the links of the BSS connection but doesn't tell the driver about that, as it thinks that this vif is not in the driver. 8. in ieee80211_stop_device, *ALL* wiphy works are getting flushed (erroneously?) 9. Therefore, async_handlers_wk is being executed, processing the statistics notification that was received after we restored the BSS connection. 10. the notification handler dereferences fw_id_to_bss_conf[id], which is now a dangling pointer, as mac80211 already freed this link in (7). 11. On the first access to one of the links fields, we panic. While this can and should be fixed by removing the call to ieee80211_handle_reconfig_failure in (6), it is also not a good idea to carry and maybe handle notifications from a dead FW. We do purge the notifications when we stop the FW, but in reconfig failure we stop the FW too late, after the notifications are processed. In addition, async_handlers_wk can always be scheduled before the reconfig work. Purge the notifications immediately when transport notifies about a nic error.

  10. CVE-2026-97473 – Non évaluée

    Linux

    In the Linux kernel, the following vulnerability has been resolved: powercap: intel_rapl: Fix memory leak in rapl_add_package_cpuslocked() When topology_physical_package_id()/topology_logical_die_id() returns a negative value, rapl_add_package_cpuslocked() returns ERR_PTR(-EINVAL) directly without freeing the rapl_package structure that was just allocated by kzalloc_obj(), leaking memory on every failed package addition. Use the existing err_free_package label so that the allocation is released on the error path.
