add patch from upstream to add missing privilege check
from the advisory:
Malicious or misbehaving unprivileged guests can cause the host or other
guests to malfunction. This can result in host-wide denial of service.
Privilege escalation, while seeming to be unlikely, cannot be excluded.
Only PV guests can take advantage of this vulnerability.
