CVE-2025-40334 [MEDIUM] CWE-1285 kernel: drm/amdgpu: validate userq buffer virtual address and size
kernel: drm/amdgpu: validate userq buffer virtual address and size
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: validate userq buffer virtual address and size
It needs to validate the userq object virtual address to
determine whether it is residented in a valid vm mapping.
An input validation vulnerability was found in the AMD GPU driver in the Linux kernel. The user queue (userq) buffer virtual address and size are not properly validated to ensure they reside within a valid VM mapping. This could allow a local user to provide invalid addresses, potentially causing memory corruption or system crashes.
Statement: This is an input validation issue in the AMD GPU driver's user queue handling. The impact requires local access with GPU access permissions an
