How to fix?

Upgrade Echo:latest libvirt to version 6.0.0-2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libvirt package and not the libvirt package as distributed by Echo. See How to fix? for Echo:latest 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).
