CVE-2026-74358

CVE-2026-74358 concerns the Linux kernel ext4 fast-commit wait/wake bit mapping on 64-bit. The vulnerability arises because ext4 dynamic inode states live in the upper half of i_flags on 64-bit, and ext4_test_inode_state() applies a +32 offset. The fast-commit wait and wake paths previously used ...

CVE-2026-74357

CVE-2026-74357 (Linux kernel, amdgpu) : The vulnerability arises in the amdgpu_coredump path where two passes over adev->rings[] count and copy ring data using the same skip condition. Because last_seq is updated concurrently by the fence signalling path, rings may transition from signalled to...

CVE-2026-74356

CVE-2026-74356 concerns the Linux kernel vhost subsystem. The issue is that vhost_get_avail_idx incorrectly reported whether all entries were consumed instead of whether new entries were added to the virtqueue, particularly affecting drivers/vhost/net.c when mergeable buffers are enabled. This mi...

CVE-2026-74355

In the Linux kernel vulnerability CVE-2026-74355, the issue occurs in iommu/vt-d where the info->node RB-tree is zero-initialized via kzalloc. If ATS is not supported, device_rbtree_insert() is skipped, and on a later failed probe step, device_rbtree_remove() can misinterpret the zeroed node a...

CVE-2026-74354

CVE-2026-74354 : In the Linux kernel, a vulnerability in the BPF zap_pages path is resolved by changing how mmap_lock is taken for zap_vma_range(). The root cause is that zap_vma_range() requires the owning mm’s mmap_lock to be held, and taking mmap_read_lock under arena->lock could AB-BA agai...

CVE-2026-74353

The CVE-2026-74353 entry concerns the Linux kernel component drm/amdkfd. The issue arises from an incorrect flow around suspend_all/resume_all: the fix ensures that queues are restored even if suspend_all fails and that remove_queue is always run because it can trigger a GPU reset if removing the...

CVE-2026-74352

In the Linux kernel vulnerability CVE-2026-74352, the issue arises when alloc_reserved_mem_array() fails, causing reserved_mem to continue pointing to reserved_mem_array in __initdata. This could enable a post-init use-after-free via of_reserved_mem_lookup() which is exported for post-init use. T...

CVE-2026-74351

CVE-2026-74351 affects the Linux kernel OCFS2 locking state. The root cause is a use-after-free risk where the debugfs iterator copies ocfs2_lock_res with a non-NULL sb_lvbptr that still points to an original lockres owner after teardown, leading to a freed container being accessed during dump. T...

CVE-2026-74350

CVE-2026-74350 describes a vulnerability in the Linux kernel OCFS2 fast symlink handling. If a zero-cluster fast symlink inode has an i_size that exceeds the inline payload capacity or its payload is not exactly NUL-terminated at i_size, a memcpy during read can read past the inode block buffer, ...

CVE-2026-74349

The CVE-2026-74349 issue affects the Linux kernel’s OCFS2 filesystem, where FITRIM range handling incorrectly validated ranges that cross cluster boundaries. Specifically, ocfs2_trim_mainbm() trims the global bitmap in cluster units but only validates ranges against sb->s_blocksize; on filesys...

CVE-2026-74347

This CVE concerns the Linux kernel netfilter cttimeout handling. The fix adds a refcount for struct nf_ct_timeout used by the ct extension to track whether a conntrack entry uses the custom timeout policy, and then removes the control-plane refcount so the timeout policy can be removed immediatel...

CVE-2026-74348

CVE-2026-74348 affects the Linux kernel, specifically the ocfs2/dlm path for locking_state debugfs opens. The root cause is that debug_lockres_open() calls dlm_grab(dlm) but ignores its return value; after the last domain unregisters, dlm_grab() can return NULL, yet open stores the raw pointer an...

CVE-2026-74346

CVE-2026-74346 pertains to the Linux kernel RDMA/irdma subsystem, fixing an OOB read during CQ MR registration. The root cause was that the cqmr->split field, which indicates IRDMA_FEATURE_CQ_RESIZE, was not reliably set at MR registration time. The fix eliminates the cqmr->split field and ...

CVE-2026-74344

CVE-2026-74344 affects the Linux kernel BPF RB-tree code. The vulnerability arises in bpf_rb_root_free() when detaching the root: the function copies rb_root_cached, replaces the live root with RB_ROOT_CACHED, and then walks the copied tree to drop objects. If a dropped object is refcounted and s...

CVE-2026-74345

The CVE-2026-74345 entry describes a Linux kernel vulnerability in the RDMA/siw driver where disassociating a socket from an endpoint may release the last reference to the endpoint, leading to a use-after-free if the endpoint’s socket pointer is cleared after the disassociation. The fix ensures t...

CVE-2026-74343

CVE-2026-74343 describes a Linux kernel kernfs xattr race: multiple inodes across different superblocks can share kernfs_node->iattr->xattrs, and VFS per-inode locks are not enough to serialize concurrent xattr modifications. The fix introduces per-node hashing mutexes (renaming open_file_m...

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...
