A double free memory issue was found to occur in the libvirt API responsible
for requesting information about network interfaces of a running QEMU domain.
This flaw affects the polkit access control driver. Specifically, clients
connecting to the read-write socket with limited ACL permissions could use this
flaw to crash the libvirt daemon, resulting in a denial of service, or
