+# What is modprobe_module?
+
+modprobe_module is a simple script that validates it won't be possible to access /lib/modules to load any module via modprobe inside the QM partition.
+
+# How to use it?
+
+It must be executed inside the QM partition to validate it won't be possible to modprobe any module under /lib/modules.
+
+Example:
+```
+my-host# podman exec -it qm bash
+
+bash-5.1# ./modprobe_module 
+modprobe: FATAL: Module ext4 not found in directory /lib/modules/5.14.0-447.400.el9iv.x86_64
+ls: cannot access '/lib/modules/5.14.0-447.400.el9iv.x86_64': No such file or directory
+done
+
+```
