Linux Kernel Exploitation Lab

This repository contains the materials for the Linux Kernel Exploitation Lab. Thanks to @deathNet123 for this lab. It uses qemu with debian images to simulate a kernel environment.

Setup

Make debian image

./create-image.sh -d bookworm -f full

Kernel Compilation

This script will automatically downlaod the specified kernel version and compile it with required debug symbols and configurations. For instance I have used 6.1.38 version of the kernel.

./build.sh 6.1.38 6.x

Launching the VM

./startvm

Interacting with the VM

To copy the files to the VM, you can use following command:

./copy2vm <file>

And this will copy the file to the /home/user directory of the VM.

Intstall 3rd party tool

By mounting the filesystem img file and then chroot into it.

Mount the filesystem

cd img && mkdir mountpt
sudo mount bookworm.img mountpt/

Chroot into the filesystem

cd mountpt
sudo chroot .

Install the dependencies, utilities or library

apt install <pkg-name>
