## Overview

Software installed and run as a non-privileged user may conduct improper GPU driver IOCTL calls to create an allocation scenario that when freed would cause double free and kernel heap corruption.



Scenario caused by fabricating a specific combination of flags on the allocation interface that would cause an incorrect double free event when freed.
