CVE-2026-43254 ovpn: tcp - fix packet extraction from stream

In the Linux kernel, the following vulnerability has been resolved: ovpn: tcp - fix packet extraction from stream When processing TCP stream data in ovpntcprecv, we receive large cloned skbs from strprcv that may contain multiple coalesced packets. The current implementation has two bugs: 1. Head...

CVE-2026-43199

CVE-2026-43199 affects the Linux kernel net/mlx5e component. A scheduling-while-atomic bug occurred when mlx5e_ipsec_init_macs() queried hardware MAC via mlx5_query_mac_address() from an atomic context (mlx5e_ipsec_handle_event/workqueue), which can sleep. The fix uses the MAC address already pre...

CVE-2026-43121

CVE-2026-43121 involves the Linux kernel io_uring/zcrx race between scrub and refill paths. The non-atomic read-then-decrement of the user_refs can race with io_zcrx_scrub() using atomic_xchg, causing a double-free of a niov and an out-of-bounds write past the freelist array. The fix replaces the...

CVE-2026-43115

In the Linux kernel, the following vulnerability has been resolved: srcu: Use irqwork to start GP in tiny SRCU Tiny SRCU's srcugpstartifneeded directly calls schedulework, which acquires the workqueue pool-lock. This causes a lockdep splat when callsrcu is called with a scheduler lock held, due t...

CVE-2026-43074

In the Linux kernel, the following vulnerability has been resolved: eventpoll: defer struct eventpoll free to RCU grace period In certain situations, epfree in eventpoll.c will kfree the epi-ep eventpoll struct while it still being used by another concurrent thread. Defer the kfree to an RCU...

CVE-2026-43073

A flaw was found in the Linux kernel. The copyusernocache function had a misleading name, which led to its incorrect use by certain kernel components drivers. These drivers performed kernel memory copies without properly considering the function's exception handling mechanisms. This improper usag...

CVE-2026-43092

The CVE-2026-43092 issue affects the Linux kernel AF_XDP subsystem: bind now validates MTU against the usable frame space provided by UMEM chunks. Previously, zero-copy pool configurations could be accepted without confirming that the device MTU fits into the usable frame space, considering tailr...

CVE-2026-43091

The CVE-2026-43091 vulnerability affects the Linux kernel xfrm policy handling during netns exit. The root cause is that xfrm_policy_fini() frees the policy_bydst hash tables after flushing work items and deleting policies, but does not wait for concurrent RCU readers to exit read-side critical s...
