If you're root, a local privilege escalation isn't going to get you any more privileges than you already have.

If you're root in a container, but not root on the outside system, you shouldn't be able to write to /proc/sys/kernel/modprobe, no?

I just wanted to mention that the path to modprobe is something reversible (containers aside) if the sysadmin wants autoloading. /proc/sys/kernel/modprobe is not writable from a container.

Disabling module loading is not reversible, you need to reboot.
