These days I think there is still necessity to write a tutorial series on Linux Kernel exploitation and hope to summarize the kernel exploitation techniques as following:
(1) Kernel Debugging
(2) Return-oriented-Programming in Kernel
(3) Kernel Mitigation: KASLR, SMEP, SMAP
(4) Kernel Space Memory Allocator: SLAB Allocator
In this post, I will introduce how to debug a Linux Kernel via CVE-2017-7308 , including setting up debugging environment, root cause analysis and exploit primitive analysis.
