| CVE-2026-72016 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: cpu/hotplug: Fix NULL kobject warning in cpuhp_smt_enable() On arm64, when booting with `maxcpus` greater than the number of present CPUs (e.g., QEMU -smp cpus=4,maxcpus=8), some CPUs are marked as 'present' but have not yet been registered via register_cpu(). Consequently, the per-cpu device objects for these CPUs are not yet initialized. In cpuhp_smt_enable(), the code iterates over all present CPUs. Calling _cpu_up() for these unregistered CPUs eventually leads to sysfs_create_group() being called with a NULL kobject (or a kobject without a directory), triggering the following warning in fs/sysfs/group.c: WARNING: fs/sysfs/group.c:137 at internal_create_group+0x41c/0x4bc, CPU#2: sh/181 [...] Call trace: internal_create_group+0x41c/0x4bc (P) sysfs_create_group+0x18/0x24 topology_add_dev+0x1c/0x28 cpuhp_invoke_callback+0x104/0x20c __cpuhp_invoke_callback_range+0x94/0x11c _cpu_up+0x200/0x37c When booting with ACPI, arm64 smp_prepare_cpus() currently sets all enumerated CPUs as "present" regardless of their status in the MADT. This causes issues with SMT hotplug control. For instance, with QEMU's "-smp 4,maxcpus=8" configuration, the MADT GICC entries are populated as follows: 1. The first four CPUs: `Enabled` set but `Online Capable` not set. 2. The remaining four CPUs: `Online Capable` set but `Enabled` not set to support potential hot-plugging. Fix this by: 1. When booting with ACPI, checking the ACPI_MADT_ENABLED flag in the GICC entry before calling set_cpu_present() during SMP initialization. 2. Properly managing the present mask in acpi_map_cpu() and acpi_unmap_cpu() to support actual CPU hotplug events, This aligns with other architectures like x86 and LoongArch. 3. Update the arm64 CPU hotplug documentation to no longer state that all online-capable vCPUs are marked as present by the kernel at boot time. This ensures that only physically available or explicitly enabled CPUs are in the present mask, keeping the SMT control logic consistent with the actual hardware state. | ||||
| CVE-2026-68456 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: usb: atm: ueagle-atm: wait for pre-firmware load in .disconnect() ueagle-atm uses the asynchronous request_firmware_nowait() in .probe(), but does not wait for its completion, not even in .disconnect(); so, if the device is unplugged meanwhile, its teardown runs concurrently with that. Even though this inconsistency is worth addressing on its own, it has also triggered several bug reports in syzbot over the years (some auto-closed) where the firmware sysfs fallback mechanism (CONFIG_FW_LOADER_USER_HELPER) creates a firmware subdirectory in the device directory during its removal, which might hit unexpected conditions in kernfs, apparently, depending at which point the add and remove operations raced. (See links.) The pattern is: usb ?-?: Direct firmware load for ueagle-atm/eagle?.fw failed with error -2 usb ?-?: Falling back to sysfs fallback for: ueagle-atm/eagle?.fw <ERROR> Call trace: ... kernfs_create_dir_ns sysfs_create_dir_ns create_dir kobject_add_internal kobject_add_varg kobject_add class_dir_create_and_add get_device_parent device_add fw_load_sysfs_fallback fw_load_from_user_helper firmware_fallback_sysfs _request_firmware request_firmware_work_func ... (Some variations are observed, after fw_load_sysfs_fallback(), e.g., [1].) While the kernfs side is being looked at, the ueagle-atm side can be fixed by waiting for the pre-firmware load in the .disconnect() handler. This change has a similar approach to previous work by Andrey Tsygunka [2] (wait_for_completion() in .disconnect()), but it is relatively different in design/implementation; using the Originally-by tag for credit assignment. This has been tested with: - synthetic reproducer to check the error path; - USB gadget (virtual device) to check the firmware upload path; - QEMU device emulator to check the device ID re-enumeration path; (The latter two were written by Claude; no other code/text in this commit.)

| CVE-2026-74422 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: drm/rockchip: inno-hdmi: Switch to drmm_kzalloc() Driver makes use of drmm_encoder_init() to initialize the encoder and automatically handle the cleanup by registering drm_encoder_cleanup() with drmm_add_action(). However, the internal structure containing the encoder part gets allocated with devm_kzalloc(), which happens while component_bind_all() is being called from Rockchip DRM driver. The component framework further ensures it is deallocated as part of releasing all the resources claimed during bind, which is triggered from component_unbind_all(). When the reference to the DRM device gets eventually dropped via drm_dev_put() in rockchip_drm_unbind(), drmm_encoder_alloc_release() attempts to access the now released encoder structure, leading to use-after-free. Ensure driver's internal structure is still reachable on encoder cleanup by switching from a device-managed allocation to a drm-managed one. | ||||

| CVE-2026-74375 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: md/raid1,raid10: fix deadlock in read error recovery path raid1d and raid10d may resubmit a split md cloned bio while handling a read error. In this case, resubmitting the bio can lead to a deadlock if the array is suspended before md_handle_request() acquires an active_io reference via percpu_ref_tryget_live(). Since the cloned bio already holds an active_io reference, trying to acquire another reference via percpu_ref_tryget_live() can lead to a deadlock while the array is suspended. Fix this by using percpu_ref_get() for md cloned bios. | ||||
| CVE-2026-74366 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix NULL deref in change_sta_links for unready link _ieee80211_set_active_links() calls _ieee80211_link_use_channel() for each newly-added link and WARN_ON_ONCE()s if it fails. The call uses assign_on_failure=true, which allows mac80211 to continue despite driver failures, but when a mac80211-level channel validation fails (e.g., combinations check, DFS, or no available radio), drv_assign_vif_chanctx() is never reached. Since ath12k_mac_vdev_create() is only called from that path, arvif->is_created remains false and arvif->ar remains NULL for the failed link. The subsequent drv_change_sta_links() call reaches ath12k_mac_op_change_sta_links(), which allocates an arsta and sets ahsta->links_map |= BIT(link_id) for the broken link before checking whether the link is ready. When the vdev was never created, only station_add() is skipped, but the link remains in links_map. Any subsequent operation iterating links_map and dereferencing arvif->ar without a NULL check will crash. Two observed examples are NULL deref in ath12k_mac_ml_station_remove() on disconnect and in ath12k_mac_op_set_key() when wpa_supplicant installs PTK keys.

This prevents the broken link from entering links_map, so all subsequent operations iterating the bitmap are protected. The reliability of arvif->is_created across all error paths is ensured by the preceding patch. Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00302-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.115823.3 | ||||
| CVE-2026-74337 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Fix NMI/tracepoint re-entry deadlock on lru locks NMI and tracepoint BPF programs can re-enter the per-CPU or global LRU lock that bpf_lru_pop_free()/push_free() already hold on the same CPU, AA-deadlocking. Lockdep reports "inconsistent {INITIAL USE} -> {IN-NMI}" on &l->lock (syzbot c69a0a2c816716f1e0d5) and "possible recursive locking detected" on &loc_l->lock (syzbot 18b26edb69b2e19f3b33). Prior trylock and rqspinlock based fixes (see links) were nacked because compromised on reliability. This patch converts every LRU lock site to rqspinlock_t and adds a recovery path for some failure windows to avoid node leaks. Failure recovery: - *_pop_free top-level: return NULL; prealloc_lru_pop() already treats that as no-free-element (-ENOMEM). - Cross-CPU steal: skip the victim's locked loc_l, try next CPU. - Post-steal local lock fail: publish stolen node to lockless per-CPU free_llist; next pop on this CPU picks it up. - push_free fail: mark node pending_free=1. __local_list_flush(), __local_list_pop_pending() reclaim the node from pending_list. __bpf_lru_list_shrink_inactive() reclaims the node from inactive list. Nodes from active list are reclaimed by __bpf_lru_list_shrink() or after __bpf_lru_list_rotate_active() demotes it to the inactive. | ||||
| CVE-2026-74331 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: firmware_loader: Fix recursive lock in device_cache_fw_images() A recursive locking deadlock can occur in the firmware loader's power management notification handler. During system suspend or hibernation preparation, fw_pm_notify() calls device_cache_fw_images(). This function acquires fw_lock to set the firmware cache state to FW_LOADER_START_CACHE and then iterates over all devices using dpm_for_each_dev() while still holding the lock. For each device, dev_cache_fw_image() schedules asynchronous work to cache the firmware. If memory allocation for the async work entry fails (e.g., in out-of-memory conditions), async_schedule_node_domain() falls back to executing the work function synchronously in the current thread. The synchronous execution path (__async_dev_cache_fw_image() -> cache_firmware() -> request_firmware() -> assign_fw()) attempts to acquire fw_lock again. Since the current thread already holds fw_lock, this results in a recursive locking deadlock. Fix this by releasing fw_lock immediately after updating the cache state and before calling dpm_for_each_dev(). The lock is only needed to protect the state update. Concurrent firmware requests will correctly see the FW_LOADER_START_CACHE state and use the piggyback mechanism, which is independently protected by its own fwc->name_lock. | ||||
| CVE-2026-74290 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: net/sched: cls_flow: Dont expose folded kernel pointers The flow classifier falls back to addr_fold() for fields that are missing from packet headers. In map mode, userspace controls mask, xor, rshift, addend and divisor, and can observe the resulting classid through class statistics. This allows a tc classifier in a user/network namespace to recover the 32-bit folded value of skb->sk, skb_dst() or skb_nfct(). Align with standard kernel practices for pointer hashing and replace the XOR folding with a keyed siphash (which is cryptographically secure) | ||||

| In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Avoid displaying the kernel pointer While dumping the info on MR using the rdma tool, we dump the mr_hwq which is a kernel pointer. There is no need to expose this value for end user. So avoid it. | ||||
| CVE-2026-72484 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: staging: most: video: avoid double free on video register failure comp_register_videodev() allocates a video_device with video_device_alloc() and releases it if video_register_device() fails. This can double free the video_device when __video_register_device() reaches device_register() and that call fails: video_register_device() -> __video_register_device() -> device_register() fails -> put_device(&vdev->dev) -> v4l2_device_release() -> vdev->release(vdev) -> video_device_release(vdev) comp_register_videodev() -> video_device_release(mdev->vdev) Use video_device_release_empty() while registering the device so that registration failure paths do not free mdev->vdev through vdev->release(). comp_register_videodev() then releases mdev->vdev exactly once on failure. Restore video_device_release() after successful registration so the registered device keeps its normal lifetime handling. This issue was found by a static analysis tool I am developing. | ||||
| CVE-2026-72467 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: xprtrdma: Check frwr_wp_create() during connect frwr_wp_create() creates the singleton Memory Region used to encode padding for Write chunks whose payload length is not XDR-aligned. Its failure paths return a negative errno and leave ep->re_write_pad_mr set to NULL. rpcrdma_xprt_connect() currently ignores that return value. If frwr_wp_create() fails after the rest of the connection setup succeeds, xprt_rdma_connect_worker() treats the connection attempt as successful and sets XPRT_CONNECTED. A later NFS/RDMA read with a non-4-byte-aligned receive page length reaches rpcrdma_encode_write_list(), passes the NULL write-pad MR to encode_rdma_segment(), and dereferences it. This is locally triggerable on an NFS/RDMA client after a connect or reconnect hits a local MR allocation, DMA-map, MR-map, or post-send failure; a remote peer alone cannot force the local MR setup failure. Check the return value and fail the connect as -ENOTCONN, matching the adjacent setup failures. This keeps XPRT_CONNECTED clear and lets the normal reconnect path retry. | ||||
