Part 4/5:

By corrupting the page table entry to point to the base address of the kernel, the researchers were able to overwrite the mod_probe_path in the kernel, which is a path that executes a binary when a kernel module is loaded. Instead of running the legitimate mod_probe binary, the researchers' arbitrary code would be executed with root privileges, completely compromising the system.

This exploit is a true testament to the ingenuity and technical prowess of the security researchers who discovered it. The techniques used, such as the double-free in the kernel, the arbitrary allocation of page table entries, and the bypass of various defenses, are truly remarkable and push the boundaries of what's possible in the world of kernel exploitation.
