Buffer Eviction Vulnerability in Linux Kernel AMD Graphics Driver

CVE-2026-97498

What is CVE-2026-97498?

A vulnerability exists in the Linux kernel's AMD graphics driver related to the handling of queue core objects used in user queues. Specifically, mqd (multiqueue descriptor) and fw (firmware) objects can be evicted, leading to the hardware attempting to access invalid memory addresses. This can result in page faults and potential system hangs, compromising system stability and performance. Ensuring these critical components remain valid and mapped during eviction is essential for maintaining proper functionality.
