[corCTF 2021] Wall Of Perdition: Utilizing msg_msg Objects For Arbitrary Read And Arbitrary Write In The Linux Kernel
1.4 parsecs away

Travel
| | Wall of Perdition is the second and harder part of a two part series of kernel exploitation challenges designed by FizzBuzz101 and me for corCTF 2021. You can find the writeup for the first part, Fire of Salvation, on his blog. Unfortunately, both challenges during competition remained unsolved. Wall of Perdition consists of a vulnerable Linux Kernel Module, the bug is a 0x30 bytes Use After Free Write in kmalloc-64. With this challenge, we present a new approach to transform the Linux kernel's IPC mechanism, more specifically, message operations, in an exploitation toolkit. Let's get started!
