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! |
