"This update for drm provides the following fixes: This security issue
was fixed :

  - CVE-2017-10810: Memory leak in the
    virtio_gpu_object_create function in
    drivers/gpu/drm/virtio/virtgpu_object.c allowed
    attackers to cause a denial of service (memory
    consumption) by triggering object-initialization
    failures (bnc#1047277)

The update package also includes non-security fixes. See advisory for
details.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
