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.

CVE-2020-14374 DPDK vulnerabilities
Title: DPDK vulnerabilities
Summary: Several security issues were fixed in DPDK.
Ryan Hall discovered that DPDK incorrectly handled vhost crypto. An
attacker inside a guest could use these issues to perform multiple attacks,
including denial of service attacks, obtaining sensitive information from
the host, and possibly executing arbitrary code on the host.
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2020-14378 dpdk: partial Denial of Service due to Integer Underflow
An integer underflow in the move_desc function can lead to many 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 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.
Discussion:
Statement:
This flaw does not affect the versions of `dpdk` as shipped with Red Hat Enterprise Linux 7 and 8 or the versions embedded in Red Hat Virtualization or the Fast Datapath `openvswitch` package, as they do not enable generic crypto device library support. This causes the vulnerable code in vhost_crypto.c to not be included.
This flaw does not affe
