Theory is nothing without practice. Today, I will explain the nature of Linux kernel vulnerabilities and will shown how to exploit them. Get ready for an exciting journey: you will create your own Linux kernel module and use it to escalate your privileges to superuser. Then you’ll build a Linux kernel with a vulnerable module, prepare everything required to run the kernel in a QEMU virtual machine, and automate the kernel module loading process. Finally, you will learn how to debug the kernel and use the ROP technique to gain root privileges.
