Hi, I’m Ne0. Last weekend we Eur3kA played Nu1L CTF 2018 and won the champion. Thanks all my strong teammates. This kernel pwn challenge is not very difficult but kind of tricky. Thanks @Anciety’s help.
Challenge info The challenge files includes the following:
➜ network_card ls bzImage initramfs.img nu1l.ko startvm.sh Obviously we should focus on nu1l.ko. Take a look at the startvm.sh and we will find that we have to bypass kaslr,smep and smap to solve this challenge.
