CVE-2026-80667

CVE-2026-80667 affects the Linux kernel's mlx5 driver (used by Mellanox/NVIDIA ConnectX network adapters), specifically the LAG (Link Aggregation Group) and MPESW (Multi-Packet Steering) subsystem. The root cause is that mlx5_mpesw_work() could return without calling complete() when mlx5_lag_get_...

CVE-2026-80668

A race condition in the Linux kernel's netfilter nf_conntrack_expect subsystem allows an expectation to access a stale exp->master pointer when expectation removal loses a race with an expiring timer (timer_del() reporting false). The fix replaces the timer-based expiration with the existing c...
