About this tag
The amdgpu security tag on WindowsForum.com covers vulnerabilities and fixes in the AMDGPU Linux graphics driver, particularly race conditions and memory management issues. Recent discussions focus on CVE-2026-31462, a PASID reuse race that can cause GPU instability when multiple compute contexts are active. The kernel fix addresses this by changing PASID allocation to a cyclic scheme, reducing the likelihood of immediate reuse while old page-fault activity drains. This tag is relevant for Linux users, system administrators, and developers tracking security patches for AMD graphics hardware.

    AMDGPU CVE-2026-31462: PASID Reuse Race Fix Stops GPU Instability

    In the Linux graphics stack, CVE-2026-31462 is a reminder that even a small ordering bug in an advanced driver can ripple into visible instability, especially when the GPU is juggling multiple compute contexts in rapid succession. The flaw in drm/amdgpu centers on PASID reuse, where a newly...
