CVE-2026-46042 concerns a Linux kernel memory-leak issue in mm/mempolicy (weighted_interleave_auto_store) that leaks old/new wi_state under certain input paths; the fix moves the old_wi_state fetch to an unconditional location, enabling a unified early return when the requested mode matches the c...

CVE-2026-46047

CVE-2026-46047: In the Linux kernel, net: qrtr: ns use-after-free in driver remove is fixed. The vulnerability arises if a packet arrives after destroy_workqueue() but before sock_release(), causing qrtr_ns_data_ready() to queue a work item that dereferences freed memory. Root and distro advisori...

CVE-2026-46079

CVE-2026-46079 concerns the Linux kernel RBD path. The issue arises when device_add_disk() is followed by a failure in device_add_disk(); the code can call rbd_free_disk() twice and then rbd_dev_device_release(), causing a null-ptr-deref in __blk_mq_free_map_and_rqs() during blk-mq cleanup. The f...

CVE-2026-46231

CVE-2026-46231 concerns the Linux kernel’s batman-adv code. When batadv_bla_add_claim() fails to insert a new claim into its hash, a reference to the target backbone_gw could be leaked.

CVE-2026-46239

CVE-2026-46239 affects the Linux kernel media: i2c: ov5647 driver. Concrete issue: three control paths (AUTOGAIN, EXPOSURE_AUTO, ANALOGUE_GAIN) return early without pm_runtime_put(), leaking runtime PM references. The patch changes these cases from return to a ret = ... break pattern to ensure pm...

CVE-2026-46283

In the provided sources, CVE-2026-46283 affects the Linux kernel TPM subsystem, where tpm_dev_release() frees sensitive material (chip->auth) with plain kfree() instead of kfree_sensitive(). This leaves HMAC session keys, nonces, and passphrase data potentially scrubbed only later in memory, u...

CVE-2026-52906

CVE-2026-52906 (Linux kernel 9p/v9fs) : The issue arises from how 9p options are applied during mounts. After commit 1f3e4142, v9fs_apply_options() uses |= to combine new flags with those already set by v9fs_session_init(), which for 9P2000.L defaults to V9FS_ACCESS_CLIENT. When a user mounts wit...

CVE-2026-52932

In CVE-2026-52932, the Linux kernel xfrm IPcomp path contains a fix to ensure that the allocated destination scatter-gather (dst SG) list is freed on error as well as on success, preventing potential resource leaks. The root cause is improper memory deallocation during error handling in the xfrm ...

CVE-2026-53041

CVE-2026-53041 concerns OCFS2 in the Linux kernel. When an OCFS2 inode has both inline and block-based xattrs, listxattr() could report a size larger than the caller’s buffer if inline names consumed the buffer exactly, triggering a kernel bug/DoS. The root cause was a refactor that used size == ...

CVE-2026-53130

The CVE-2026-53130 issue affects the Linux kernel OMFS code path (fs/omfs). A crafted filesystem image with s_sys_blocksize b_data + OMFS_DIR_START due to an unsigned underflow. The result can overwrite kernel memory far beyond the backing block buffer. The advisory notes a fix: add a lower-bound...

CVE-2026-53148

The CVE affects the Linux kernel Thunderbolt driver (tb_xdp_properties_request) where per-packet copy length is derived from the response header without bounds checking against the allocated data buffer, causing a potential out-of-bounds memcpy and memory corruption. The issue can lead to denial ...

CVE-2026-53276

The CVE-2026-53276 entry concerns the Linux kernel Bluetooth ISO stack. A use-after-free occurs in iso_sock_rebind_bc where the bis pointer is cached and the socket lock is released before traversals, allowing a concurrent close() to free the hci_conn and its bis structure. The code then accesses...
