CVE-2020-14378

dpdk: partial Denial of Service due to Integer Underflow

Published Sep 30, 2020 CVSS 3.1 · 3.3 Low EPSS < 1% KEV · Not listed
Description
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.
