+  * virdevmapper: Don't use libdevmapper to obtain dependencies
+
+    When building domain's private ``/dev`` in a namespace, libdevmapper was
+    consulted for getting full dependency tree of domain's disks. However, this
+    meant that libdevmapper opened ``/dev/mapper/control`` which wasn't closed
+    and was leaked to QEMU. CVE-2020-14339
