CVE-2021-3546

An out-of-bounds write vulnerability was found in the virtio vhost-user GPU
device (vhost-user-gpu) of QEMU in versions up to and including 6.0. The
flaw occurs while processing the ‘VIRTIO_GPU_CMD_GET_CAPSET’ command from
the guest. It could allow a privileged guest user to crash the QEMU process
on the host, resulting in a denial of service condition, or potential code
execution with the privileges of the QEMU process.
