NVD Description

Note: Versions mentioned in the description apply only to the upstream libvirt-daemon-driver-storage-mpath package and not the libvirt-daemon-driver-storage-mpath package as distributed by SLES. See How to fix? for SLES:15.1 relevant fixed versions and status.

A use-after-free flaw was found in libvirt. The qemuMonitorUnregister() function in qemuProcessHandleMonitorEOF is called using multiple threads without being adequately protected by a monitor lock. This flaw could be triggered by the virConnectGetAllDomainStats API when the guest is shutting down. An unprivileged client with a read-only connection could use this flaw to perform a denial of service attack by causing the libvirt daemon to crash.
