This challenge analyzes a vulnerable kernel module with a /proc interface as a safe user-space simulation. Find the special command in the supplied driver-source excerpt, pass it to the simulator, and inspect its result. No real module is loaded and no credentials are changed.
Inspect MAGIC_STRING in /opt/module-sim/vulnerable.c
Use /usr/local/bin/module-sim rather than a real /proc/vulnerable interface
After passing the correct command, inspect module-result.txt in your home directory
