What is CVE-2026-99261?

The Linux kernel has been updated to address a vulnerability specifically within the AMD graphics stack related to user queue buffer overflow risk. This flaw impacts the eviction process for per-VM (Virtual Machine) buffer objects, leading to potential security issues. It ensures that the reservation fence slots for the user queue are correctly handled during object eviction, thereby mitigating the risks associated with overflow and improper fence addition that might occur during eviction. Applying the latest kernel updates is essential for maintaining system integrity and security.
