+Subject: [PATCH 1/8] block: do not pass disk names as format strings
+
+Disk names may contain arbitrary strings, so they must not be interpreted
+as format strings. It seems that only md allows arbitrary strings to be
+used for disk names, but this could allow for a local memory corruption
+from uid 0 into ring 0.
