CVE-2026-64344

CVE-2026-64344 tracks a Linux kernel USB idmouse driver use‑after‑free on disconnect race. The root cause: mutex_unlock() may touch the mutex after unlocking, risking lifetime management problems; the fix uses a kref to release driver data to avoid use‑after‑free when release() races with disconn...
