CVE-2026-46213

A flaw was found in the Linux kernel's Apple keyboard driver (appletb-kbd). A Use-After-Free (UAF) vulnerability exists in the inactivity-timer cleanup path during driver tear-down. This can occur due to race conditions between device cleanup and timer operations, or late event callbacks re-arming the timer. A local attacker could potentially exploit this to cause memory corruption, leading to system instability or a denial of service.
