CVE-2026-63981
A flaw was found in the Linux kernel's net/sched: actmirred component. An unprivileged local user, by leveraging user namespaces to gain network administration capabilities, can create a specific network configuration that triggers an unbounded recursion. This recursion bypasses a depth limit...
