CVE-2026-46311

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the drm/amdgpu/userq component where stale wptr mapping is accessed. This occurs when the wptr obj is unmapped while queue creation is in progress, allowing another buffer object (bo) to be passed at the same address. The fix involves using drm exec to properly acquire locks for both the vm root bo and the wptr obj bo to ensure mapping data is accessed correctly.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
