CVE-2026-65584

GPU DDK - Stack Buffer Overflow via undersized UFO address array in DumpStalledContextInfo

No exploitation reported by the sources we read.

Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

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.
