User Space Interaction Vulnerability in AMD Graphics Driver

CVE-2026-80541

What is CVE-2026-80541?

A vulnerability has been identified in the AMD graphics driver (AMDGPU) within the Linux kernel due to improper validation of domain combinations during user space interactions. Specifically, the driver allows users to input multiple domain types simultaneously, which could lead to unexpected behaviors and potential system instability. Proper checks are needed to ensure that only valid combinations are allowed, while enforcing that non-standard domains must be specified separately. This flaw can potentially be exploited to bypass normal operational restrictions, affecting system performance and security.
