In this talk, Dmitry will talk about progress and new developments since last year; share the current test coverage and what's not being covered. Then, talk about testability of kernel subsystems, do's and don'ts. Introduction In this paper, the author finds that, besides the running status, the non-code descriptions in CVE and Linux git logs can also help the fuzzer to avoid unnecessary runs, saving a lot of time in the fuzzing process. In particular, we use the semantics-based approach e.g., NLP to automatically analyse the description and extract.

We’ll investigate the microkernel design of Magenta along with its capability-based. In the previous part, I give an introduction on how to create an ubuntu image for QEMU. However, after beginning to analyse the qemu vulnerability I feel the debugging process is very uncomfortable. What I prefer is just a terminal of QEMU with a guest running on that. This makes me recall what I do on Syzkaller fuzzer.
