| | | | | 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 kern... | |
