An integer underflow in the move_desc function can lead to many cpu cycles being eaten up in a long running loop. An attacker could cause move_desc to get stuck in a 4,294,967,295 iteration loop. Depending on how vhost_crypto is being used this could prevent other VMs or network tasks from being serviced by the busy DPDK lcore for an extended period.
