Challenge
nc 34.80.190.155 30001
Instruction
You have a busybox shell running as user user
/home/user/rose.ko is a vulnerable kernel driver
Try exploiting /home/user/rose.ko to achieve privilege escalation
You may assumed that Busybox, the Linux kernel, and Qemu are not vulnerable.
Files
./share/rose.ko: The vulnerable driver
./src/rose.c: The source code of rose.c
Flag location
/home/user/flag
Notes
FG-KASLR is enabled
Your exploit should be kernel-agnostic. In other words, it should not rely on any kernel offsets
