# Linux kernel GPU driver: stack overflow lets local user crash system

A non-privileged local program can trigger a stack overflow in the kernel while processing GPU fence synchronization checkpoints. Successful exploitation corrupts kernel memory and typically causes a kernel crash, a denial of service.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

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.
