Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump package and not the kernel-zfcpdump package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

drm/virtio: Check whether transferred 2D BO is shmem

Transferred 2D BO always must be a shmem BO. Add check for that to prevent NULL dereference if userspace passes a VRAM BO.
