+Subject: [PATCH] Add /proc/acpi to masked paths
+
+The deafult OCI linux spec in oci/defaults{_linux}.go in Docker/Moby
+from 1.11 to current upstream master does not block /proc/acpi pathnames
+allowing attackers to modify host's hardware like enabling/disabling
+bluetooth or turning up/down keyboard brightness. SELinux prevents all
+of this if enabled.
