Local privilege escalation via stale worker reference

Use-after-free in Android 13 Vibrator.cpp allows local users to execute arbitrary code and escalate privileges through the compose method. The method starts a worker whose lambda implicitly captures the Vibrator object without retaining shared ownership, so the worker can dereference it after destruction. Low-privileged local access is required, but no user interaction is needed; successful exploitation executes code with the component's elevated privileges.
