(0Day) Google Android v4l2 Double Free Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on affected installations of Google Android. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the v4l2 driver. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this to escalate privileges in the context of the kernel.
