About this tag
CVE-2025-40334 is a locally reachable vulnerability in the AMDGPU DRM driver within the Linux kernel. It involves insufficient validation of user-provided GPU virtual addresses and buffer sizes for the user-mode queue (userq) facility. Unprivileged processes with access to DRM device nodes could trigger a kernel crash or invalid-access primitive. A defensive patch merged by upstream Linux maintainers closes this bug by adding proper validation. This tag covers discussions about the vulnerability, its impact on AMD GPU systems, and the patch that prevents kernel oops.
