| | Last month Blue Frost Security published two exploitation challenges for Ekoparty 2022. One of them was a Linux kernel challenge. I don't have much experience with Linux kernel exploitation, so this was a good opportunity to practise. I also write this up as a reference for my future self.

| In the Linux Kernel 'ring (0)' a stack is also allocated for local variables defined in functions. These functions are mainly implemented for device drivers that are defined in different Loadable Kernel Modules (LKMs). The same stack is also vulnerable to stack overflow attacks that aim at overwriting the return address saved on the stack - this post will cover exploiting these vulnerabilities.
