Note: Versions mentioned in the description apply only to the upstream libvirt-debuginfo package and not the libvirt-debuginfo package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

A flaw was discovered in libvirt in the XML file processing. More specifically, the parsing of user provided XML files was performed before the ACL checks. A malicious user with limited permissions could exploit this flaw by submitting a specially crafted XML file, causing libvirt to allocate too much memory on the host. The excessive memory consumption could lead to a libvirt process crash on the host, resulting in a denial-of-service condition.
