NVD Description

Note: Versions mentioned in the description apply only to the upstream openvswitch2.17-ipsec package and not the openvswitch2.17-ipsec package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

A flaw was found in DPDK lib/vhost. Missing length validation before reading command_data in the virtio-net control-queue handler can cause an out-of-bounds read and a host process crash.
