CVE-2026-74341

CVE-2026-74341 relates to a Linux kernel issue in the wifi wcn36xx driver where the firmware response dispatcher copies HAL responses into a 4096-byte hal_buf without validating length. Oversized responses can trigger a heap overflow with firmware-controlled content. The root cause is lack of bou...

CVE-2026-74342

The CVE-2026-74342 entries describe a Linux kernel issue in kernfs where the LSM security hook runs before kn->__parent and kn->dir.root are initialized, causing a NULL-pointer dereference in kernfs_root(kn) (triggered during the first cgroup mkdir under /sys/fs/cgroup on SELinux-enabled sy...

CVE-2026-74340

CVE-2026-74340 describes a vulnerability in the Linux kernel’s wifi: wcn36xx path where the firmware-provided rsp->count field is used as the loop bound to index into the flexible rsp->regs[] array without validating against the received message length. If count exceeds the actual data, thi...

CVE-2026-74338

CVE-2026-74338 concerns the Linux kernel: a BPF_LSM_CGROUP sleepable program could be loaded in a context where sleeping is disallowed, triggering a BUG from sleeping in an invalid context during file_open. The fix adds verifier support to reject loading sleepable BPF_LSM_CGROUP programs destined...

CVE-2026-74339

The CVE-2026-74339 entry describes a Linux kernel ALSA seq vulnerability in snd_seq_read where a queued variable-length event header could reveal a kernel address via data.ext.ptr, because the read path did not clear the temporary header pointer before copy_to_user. The fix involves clearing that...

CVE-2026-74337

CVE-2026-74337 describes a Linux kernel vulnerability where NMI/tracepoint BPF programs could re-enter per-CPU or global LRU locks held by bpf_lru_pop_free()/push_free(), causing AA-deadlock. The fix converts LRU lock sites to rqspinlock_t and adds a recovery path for failure windows to avoid nod...

CVE-2026-74336

CVE-2026-74336 concerns the Linux kernel’s wifi/mac80211 code. The vulnerability arises in ieee80211_s1g_check_tim() when parsing the S1G TIM PVB, where the end boundary used for walking encoded blocks was incorrectly computed as tim_len + 2, allowing a read past the TIM element into adjacent dat...

CVE-2026-74335

The CVE-2026-74335 issue is in the Linux kernel’s BPF helpers: bpf_task_from_vpid() dereferences NULL in task_active_pid_ns(current) when a thread is exiting and its pid namespace is cleared, leading to a NULL pointer dereference in idr_find(). The vulnerability path involves bpf/cgroup programs ...

CVE-2026-74334

The CVE-2026-74334 issue affects the Linux kernel RDMA/nldev path, where locking around mr->pd was unsafe because pd became variable under rereg_mr and touches could race. The fix uses mr->device instead of mr->pd->device and introduces an rdma_restrack_sync() operation to ensure stal...

CVE-2026-74333

CVE-2026-74333: In the Linux kernel ASoC subsystem for amd: acp-sdw-legacy, a bound check bug occurs in create_sdw_dailinks() where it iterates soc_dais beyond the allocated entries if all entries are initialized. Reports from KASAN show a slab-out-of-bounds read. The fix is to pass the allocated...

CVE-2026-74332

The CVE-2026-74332 entry relates to the Linux kernel ASoC: amd (acp-sdw-sof): Bound DAI link iteration. The issue occurred in create_sdw_dailinks() which walked sof_dais beyond allocated entries when all entries were initialized. A fix was implemented to pass the allocated entry count to create_s...

CVE-2026-74331

CVE-2026-74331 (Linux kernel) : A deadlock arises in the firmware_loader during suspend/hibernate prep due to a recursive lock on fw_lock in device_cache_fw_images(). The sequence: fw_pm_notify() updates firmware cache state to FW_LOADER_START_CACHE while holding fw_lock, then iterates devices wi...

CVE-2026-74329

The CVE-2026-74329 entry describes a Linux kernel issue in the watchdog subsystem: watchdog_register_device() may register wdd->pm_nb when WDOG_NO_PING_ON_SUSPEND is set, but watchdog_unregister_device() does not remove it, leaving an embedded notifier block on the PM notifier chain after the ...

CVE-2026-74330

The CVE-2026-74330 entry specifies a Linux kernel fix for configfs lockless traversals of ->s_children. The issue allowed cursor movement or freeing under lock protection of the parent directory, potentially enabling invalid cursor states via lseek() despite entry protection from removal. The ...

CVE-2026-74328

CVE-2026-74328 concerns the Linux kernel: an iommufd-related issue where destroying page content after detaching from a dmabuf could occur while the mutex is still in use via invalidation callbacks. The vulnerability is addressed by ensuring the page content is not destroyed until the dmabuf is f...

CVE-2026-74327

CVE-2026-74327 affects the Linux kernel vmalloc area handling. The issue is a NULL pointer dereference in is_vm_area_hugepages() because find_vm_area() can return NULL for an invalid vmalloc address; the patch adds a check on the returned pointer before dereferencing it to prevent a kernel crash....

CVE-2026-74325

CVE-2026-74325 concerns the Linux kernel’s mt76 Wi-Fi driver. The fix replaces a plain kfree() with kfree_rcu() for the offchannel mlink object in mt76_put_vif_phy_link to ensure memory is not freed while still potentially accessed under RCU. The root cause is that rcu_assign_pointer(NULL) only p...

CVE-2026-74326

The CVE-2026-74326 entry describes a resource leak in the Linux kernel WiFi subsystem for the mt76 mt7921 driver. If pcim_iomap_region() or devm_kmemdup() fail during probe, the code returns without cleaning up previously allocated resources, specifically the mt76_device created by mt76_alloc_dev...

CVE-2026-74324

Summary: CVE-2026-74324 affects Linux kernel wireless stack, specifically mt76/mt7925 testmode query handling. In mt7925_tm_query(), the response skb is copied with memcpy(evt_resp, skb->data + 8, MT7925_EVT_RSP_LEN) without validating length. MT7925_EVT_RSP_LEN is 512, so a firmware response ...

CVE-2026-74322

In the Linux kernel, the wifi/mt76 mt7996 path is affected by CVE-2026-74322. The vulnerability stems from a possible NULL pointer dereference in mt7996_mac_write_txwi_80211() when handling injected frames (e.g., radiotap) where info->control.vif can be NULL. The code originally calls ieee8021...
