Software installed and run as a non-privileged user may conduct improper GPU system calls through the DDK kernel module interface. Under unsupported use of the interface, a use-after-free condition may occur that can lead to kernel memory corruption, platform instability, or system reboot.

The weakness occurs when software references memory after it has been released. Accessing memory after free may result in corruption of valid data structures, unexpected program behaviour, process crashes, or execution of unintended operations.
