I’m writing this post because I often hear that kernel exploitation is intimidating or difficult to learn. As a result, I’ve decided to start a series of basic bugs and exercises to get you started! Prerequisites Knowledge of the Linux command line Knowing how to read and write basic C may be beneficial Being able to debug with the help of a virtual computer or another system Able to install the kernel module compilation build requirements A basic understanding of the difference between userland and kernelland could be helpful Having a basic understanding of assembly can be beneficial for future episodes For this part, I wrote a simple Linux character device , /dev/shell . This driver will take two arguments, uid and cmd , and it will execute the cmd command as the specified uid . To understand how this driver works, I’ll explain a few things! . . Dive into the fundamentals of kernel exploitation and enhance your skills with straightforward Linux challenges and practical exercises.. Kernel Exploitation, Linux Challenges, C Programming. .
