amdgpu graphics

About this tag
The amdgpu graphics tag on WindowsForum covers Linux kernel vulnerabilities in AMD's amdgpu driver, including CVE-2026-46218 and CVE-2026-31462. These flaws involve bounds checking in video decode/encode paths and PASID reuse race conditions, respectively. While not Windows-specific, these issues matter to users running Linux on AMD hardware, dual-boot workstations, or GPU-backed virtualization. Discussions highlight how GPU drivers expand the operating system's attack surface, similar to filesystems and network stacks. The tag provides technical analysis of kernel patches and their implications for system security.

  1. CVE-2026-46218: amdgpu Kernel Fix for Bounds Check in AMD Video Decode/Encode

    CVE-2026-46218 is a newly published Linux kernel vulnerability, disclosed by kernel.org on May 28, 2026, in AMD’s amdgpu graphics driver, where UVD, VCE, and VCN video paths could access indirect buffers at fixed offsets without first confirming the buffer was large enough. The fix is small, but...

  2. CVE-2026-31462: AMDGPU PASID Reuse Race Fixed with Cyclic Allocator

    CVE-2026-31462 is a small-looking Linux kernel flaw with a very specific failure mode, but it sits in exactly the kind of plumbing that can cause outsized disruption when it misbehaves. The vulnerability in drm/amdgpu is about immediate PASID reuse after a process exits, where the GPU can...
