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

Description A flaw exists in the Linux kernel’s drm/virtio subsystem. The issue involves a missing check to ensure that transferred 2D buffer objects (BO) are shared memory (shmem) objects. If a userspace process passes a video random access memory (VRAM) BO, this can lead to a NULL dereference.

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