+Subject: b43: stop format string leaking into error msgs
+
+From: Kees Cook <keescook@chromium.org>
+
+commit e0e29b683d6784ef59bbc914eac85a04b650e63c upstream.
+
+The module parameter "fwpostfix" is userspace controllable, unfiltered,
+and is used to define the firmware filename. b43_do_request_fw() populates
+ctx->errors[] on error, containing the firmware filename. b43err()
+parses its arguments as a format string. For systems with b43 hardware,
+this could lead to a uid-0 to ring-0 escalation.
+
+CVE-2013-2852
