CVE-2026-31453

The CVE-2026-31453 issue affects the Linux kernel XFS path. The root cause is use-after-free-like behavior: after xfsaild_push_item() calls iop_push(), the log item could be freed if the AIL lock is dropped, allowing a freed log item to be dereferenced by tracepoints in the switch that follow. Th...

CVE-2026-31476

In the Linux kernel component ksmbd, CVE-2026-31476 describes a logic flaw where a multichannel session binding request that fails (for example, due to a wrong password) could cause the targeted session to be marked SMB2_SESSION_EXPIRED.

The root cause is th...

CVE-2026-31604

The CVE-2026-31604 issue concerns the Linux kernel’s wifi: rtw88 driver. A memory leak arose because the driver grabbing a reference to the USB device during probe did not release it on all probe errors (e.g., descriptor parsing failures) while the interface remained bound to a driver. The fix dr...

CVE-2026-31611

CVE-2026-31611 affects the Linux kernel's ksmbd path. The flaw occurs in parse_dacl() when comparing ACE SIDs to sid_unix_NFS_mode and subsequently reading sid.sub_auth[2] as the file mode.

CVE-2026-43196

CVE-2026-43196 affects the Linux kernel PRUSS clock multiplexer path (pruss_clk_mux_setup). The issue is a double free: devm_add_action_or_reset() path frees a resource via pruss_of_free_clk_provider(), which calls of_node_put(clk_mux_np) on error, and a second of_node_put is executed after the p...

CVE-2026-43251

CVE-2026-43251 affects the Linux kernel HID prodikeys driver. A local attacker can connect a crafted USB device whose report descriptor bypasses the pm->input_ep82 check, leaving input_ep82 NULL and causing a crash (potential DoS). Multiple OSV entries show patches in rootio-linux packages for...

CVE-2026-43275

CVE-2026-43280 is a Linux kernel vulnerability in the drm/xe module where a malicious user can supply a malformed pat_index via the madvise IOCTL, triggering an out-of-bounds read from xe->pat.table due to missing bounds checking in xe_pat_index_get_coh_mode() (validated only by a call in madv...

CVE-2026-43319

CVE-2026-43319 affects the Linux kernel spidev driver. The vulnerability stemmed from inverted lock ordering between spi_lock and buf_lock across code paths (write/read use buf_lock then spi_lock; ioctl uses spi_lock then buf_lock), enabling potential deadlocks in multi-threaded access. The fix u...

CVE-2026-43353

The CVE-2026-43353 issue affects the Linux kernel i3c: mipi-i3c-hci module where the HCI DMA dequeue path (hci_dma_dequeue_xfer()) can be invoked by multiple transfers timing out concurrently.

The CVE-2026-43370 issue affects the Linux kernel DRM/AMDGPU subsystem, specifically a use-after-free race in VM acquisition. Root cause: a non-atomic vm->process_info assignment could race when parent and child processes sharing a drm_file both attempt to acquire the same VM after fork(). The...

CVE-2026-43374

Summary: CVE-2026-43374 affects the Linux kernel networking code (net: nexthop). The vuln arises when removing a nexthop from a group: remove_nh_grp_entry() publishes the new group via rcu_assign_pointer() and then immediately frees the removed entry’s percpu stats with free_percpu(), while the s...

CVE-2026-43418

CVE-2026-43418 describes a race in the Linux kernel sched/mmcid subsystem: when new tasks are created concurrently, a newly forked task is counted as an MMCID user before it is visible in thread and task lists, which can lead to an incorrect CID allocation and potentially a machine stall. The mit...

CVE-2026-43420

CVE-2026-43420 describes a race in Ceph/Linux kernel unlink handling where i_nlink is decremented before completion of async unlink, risking underrun if the updated i_nlink becomes zero.

The issue is resolved by initializing the kernel’s internal file_kattr struc...

CVE-2026-45900

The CVE-2026-45900 issue is in the Linux kernel crypto: caam module. During dpaa2_caam_probe, netdevs allocated for DPIO setup could leak if dpaa2_dpseci_dpio_setup() fails and the cleanup path in dpaa2_dpseci_free() did not consider previously allocated nets. The fix preserves the CPU mask of al...

CVE-2026-45909

CVE-2026-45909 pertains to the Linux kernel Mediatek clock-gate driver. The fix removes __initconst from mtk_gate structures because, since commit 8ceff24a... the gate structs are used at runtime, not just for initialization. Documents indicate this resolves a runtime-access issue with potentiall...

CVE-2026-45927

The CVE-2026-45927 issue affects the Linux kernel BPF subsystem. bpf_map_get_info_by_fd caches the hash of a map regardless of its frozen state, enabling a TOCTOU where a trusted loader could compare an older hash after a map is modified but before freezing. The fix returns -EPERM when the hash i...
