Syzbot CI - Continuous Patch Series Fuzzing

Explore a conference talk presenting syzbot ci, a proof-of-concept system designed to shift fuzzing left in the Linux kernel development cycle by targeting patch series during the review process. Learn how this innovative approach addresses the latency between bug introduction and discovery that has characterized traditional continuous fuzzing methods, where syzbot has reported over 13,000 findings to the Linux kernel mailing lists over 9 years. Discover the system's architecture that monitors Linux kernel mailing lists, automatically applies incoming patch series to determined base trees, and initiates targeted fuzzing campaigns on modified code paths. Understand the core assumption that focused fuzzing can uncover bugs significantly faster than broad continuous fuzzing, with preliminary results showing reports sent to over 50 patch series during their review phase as of September 2025. Gain insights into how this system tackles regressions including build/boot failures and shallow bugs that can stall broader fuzzing efforts, and participate in discussions about future directions and focus areas for improving kernel development workflows through early bug detection.
