## Overview

Software installed and run as a non-privileged user may conduct improper GPU system calls causing a stack overflow in the kernel. The overflow occurs when processing resolved Linux/Android fence synchronization checkpoints, while user checkpoints are excluded from the stack array. Successful exploitation can cause kernel memory corruption and typically results in a denial-of-service condition through a kernel crash.



The code vulnerability is a buffer write beyond the allocated array on the stack caused by copying excessive data from an internal buffer.

## Affected

- `graphics_ddk 1.18 RTM2`
- `graphics_ddk 23.2 RTM2`
- `graphics_ddk 24.2 RTM2`
- `graphics_ddk >= 25.1 RTM2 <= 25.3 RTM`
- `graphics_ddk 26.1 RTM2`
