NVD Description

Note: Versions mentioned in the description apply only to the upstream virt:rhel/libvirt-daemon-driver-nodedev package and not the virt:rhel/libvirt-daemon-driver-nodedev package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

qemu/qemu_driver.c in libvirt before 6.0.0 mishandles the holding of a monitor job during a query to a guest agent, which allows attackers to cause a denial of service (API blockage).
