CVE-2026-46319

The CVE-2026-46319 entry describes a race in the Linux kernel net/sched act_ct where rcu_read_lock is exited before refcount_inc_not_zero on ct_ft, allowing a UAF when ct_ft is freed during cleanup. This creates a local privilege-escalation risk as an attacker could observe or trigger the race wi...
