Andrey Konovalov began his 2022 LinuxSecurity Summit Europe (LSS EU) talk with a bold statement: "fuzzing isuseless". As might be guessed, he qualified that assertion quickly byadding "without dynamic bug detectors". These bug detectors include"sanitizers" of various sorts, such as the Kernel AddressSanitizer (KASAN), but there are others. Konovalov looked in detail at KASANand gave an overview of thesanitizer landscape along with some ideas of ways to push these bugdetectors further-to find even more kernel bugs.
