Syzkaller is an unsupervised, coverage-guided fuzzer designed to uncover vulnerabilities in kernel environments, and it supports multiple operating systems including FreeBSD, Fuchsia, gVisor, Linux, NetBSD, OpenBSD, and Windows. Initially created to focus on fuzzing the Linux kernel, its functionality has broadened to support a wider array of operating systems over time. When a kernel crash occurs in one of the virtual machines, syzkaller quickly begins the process of reproducing that crash. By default, it utilizes four virtual machines to carry out this reproduction and then strives to minimize the program that triggered the crash. During this reproduction phase, fuzzing activities may be temporarily suspended, as all virtual machines could be consumed with reproducing the detected issues. The time required to reproduce a single crash can fluctuate greatly, ranging from just a few minutes to possibly an hour, based on the intricacy and reproducibility of the crash scenario. This capability to minimize and evaluate crashes significantly boosts the overall efficiency of the fuzzing process, leading to improved detection of kernel vulnerabilities. Furthermore, the insights gained from this analysis contribute to refining the fuzzing strategies employed by syzkaller in future iterations.
