CVE-2026-65584: GPU DDK - Stack Buffer Overflow via undersized UFO address array in DumpStalledContextInfo
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.
Event History
Frequently Asked Questions
Does exploitation require root or administrator privileges?
No. The issue can be triggered by software installed and run by a non-privileged user through improper GPU system calls.
Which platforms are implicated by the affected synchronization processing?
The vulnerable processing involves resolved fence synchronization checkpoints on Linux and Android.
