How to fix?

Upgrade Debian:unstable dpdk to version 19.11.5-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream dpdk package and not the dpdk package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

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.
