Kernel Exploitation With A File System Fuzzer

Another research about fuzzing the kernel via mounting corrupted filesystems. In the first part they describe the approach, but the slides could be better, so it's hard to understand what exactly they're doing (something based on Janus [1]?). The second part discusses the exploitability of some of the found bugs and demos RIP control for one of them.
