CVE-2020-14378: security - DPDK security advisory for multiple vhost crypto issues
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.
