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...

CVE-2026-80664

CVE-2026-80664 affects the Linux kernel's netfilter xt_nat module . The SNAT and DNAT target handlers assume IP-family conntrack state is present and can trigger a NULL pointer dereference in nf_nat_setup_info() when instantiated from an unsupported family (e.g., bridge) via nft_compat. The fix r...

CVE-2026-80661

CVE-2026-80661 affects the Linux kernel UFS tracing subsystem (drivers/ufs/core/ufs_trace.h). The root cause is an illegal pointer dereference in TP_printk(): the function reads the dev_name by dereferencing a saved hba pointer from the ring buffer, but TP_printk() executes when /sys/kernel/traci...
