You could open the /proc/sys/net/ipv4/conf/<if>/<whatever> file, then wait for interface to go away, try to grab as much memory as possible in hope to hit the (kfreed) ctl_table. Then fill it with pointers to your function. Then do read from file you've opened and if you are lucky, you'll get it called as ->proc_handler() in kernel mode. So this is at least an Oops and possibly more. It does depend on an interface going away though, so less of a security risk than it would otherwise be.
