[PATCH] raw_sendmsg DoS (CAN-2005-2492)
Fix unchecked __get_user that could be tricked into generating a memory read on an arbitrary address. The result of the read is not returned directly but you may be able to divine some information about it, or use the read to cause a crash on some architectures by reading hardware state. CAN-2005-2492. Fix from Al Viro, ack from Dave Miller. Signed-off-by: Chris Wright <chrisw@osdl.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
