From 7bcf9d172920a6ff29a4fd3f4c6ba93c6ee7e8c3 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Fri, 19 Nov 2010 02:12:48 +0000 Subject: [PATCH] af_802154: Disable auto-loading as mitigation against local exploits Recent review has revealed several bugs in obscure protocol implementations that can be exploited by local users for denial of service or privilege escalation. We can mitigate the effect of any remaining vulnerabilities in such 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 'af_802154' (IEEE 802.15.4) protocol is not widely used, was not present in the 'lenny' kernel, and seems to receive only sporadic maintenance. Therefore disable auto-loading.
