They can also modify the kernel to backdoor the system on the next reboot. The feature in mainline is essentially the same as the one I had: it only prevents loading modules after the point you specify, until a reboot. If being able to load modules at all is a problem, then just disable module support. Otherwise, you need to be using RBAC.
