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.

Unprivileged users with a read-only connection could abuse this flaw to crash the libvirt daemon resulting in a potential denial of service.
