Linux Kernel Vulnerability in AMD Graphics Driver Affects System Stability

CVE-2026-80728

What is CVE-2026-80728?

A fault in the Linux kernel's AMD graphics driver has been identified, which can lead to kernel page faults during device initialization. This issue occurs due to improper resource management within the driver when the aperture devres node is registered post-DRM device node. Consequently, the unmapping of the aperture may take place before the necessary cleanup routines are executed, potentially leading to a failure during probe operations. This could significantly impact system stability and graphics performance, necessitating immediate attention from affected users to ensure driver updates are applied.
