By being in the USER Space, it cannot be done. Since, kernel does such operations in KERNEL space.

Couldn't he write a fake kernel module, one of these "Hello World" examples, and load that as a module?
Via ioctl calls the user app could communicate with that module. Only I don't know what message is there to catch in kernel space.
Bus Error: Passengers dumped. Hech gap yo'q.
