How to fix?

There is no fixed version for RHEL:9 dpdk-doc.

NVD Description

Note: Versions mentioned in the description apply only to the upstream dpdk-doc package and not the dpdk-doc package as distributed by RHEL. See How to fix? for RHEL:9 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.
