How to fix?

Upgrade data_plane_development_kit to version 18.11.10, 19.11.5 or higher.

Overview

Affected versions of this package are vulnerable to Integer Underflow. An integer underflow in dpdk versions before 18.11.10 and before 19.11.5 in the move_desc function can lead to large amounts of 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-count 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.
