3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Kees Cook <[email protected]> commit 3594f4c0d7bc51e3a7e6d73c44e368ae079e42f3 upstream. The exposed interface for cm_notify_event() could result in the event msg string being parsed as a format string. Make sure it is only used as a literal string.
