Description Prasad Pandit 2017-07-05 19:28:31 UTC

Linux kernel built with the VirtIO GPU driver(CONFIG_DRM_VIRTIO_GPU) support
is vulnerable to a memory leakage issue. It could occur while creating a virtio
gpu object in virtio_gpu_object_create().

A user/process could use this flaw to leak host kernel memory potentially
resulting in DoS.
