A flaw was found in qemu. A host privilege escalation issue was found in the virtio-fs shared file system daemon where a privileged guest user is able to create a device special file in the shared directory and use it to r/w access host devices.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
