NVD Description

Note: Versions mentioned in the description apply only to the upstream libvirt-daemon-driver-storage-disk package and not the libvirt-daemon-driver-storage-disk package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

A NULL pointer dereference was found in the libvirt API responsible introduced in upstream version 3.10.0, and fixed in libvirt 6.0.0, for fetching a storage pool based on its target path. In more detail, this flaw affects storage pools created without a target path such as network-based pools like gluster and RBD. Unprivileged users with a read-only connection could abuse this flaw to crash the libvirt daemon, resulting in a potential denial of service.
