Some notes:

- I did NOT solve this challenge during the event, because of some logistic problem, in fact, i have already saw the solution from the following writeup:
* [https://ctftime.org/writeup/18660](https://ctftime.org/writeup/18660)

- The purpose of this writeup is to add some background to kernel exploitation that is missing from the original writeup and that i want to share otherwise is just for me
