+Subject: dccp: Disable auto-loading as mitigation against local exploits
+Forwarded: not-needed
+
+We can mitigate the effect of vulnerabilities in obscure protocols by
+preventing unprivileged users from loading the modules, so that they
+are only exploitable on systems where the administrator has chosen to
+load the protocol.
+
+The 'dccp' protocol is not actively maintained or widely used.
+Therefore disable auto-loading.
