Use-after-free in the Android kernel Camera component allows local users with System execution privileges to gain higher privileges. A race permits Camera memory to be freed while it remains in use, but Google has not disclosed the affected function or object. Exploitation requires local System execution privileges and no user interaction; the demonstrated consequence is privilege escalation.
