syzkaller - kernel fuzzer

syzkaller is an unsupervised coverage-guided kernel fuzzer.
Supported OSes: Akaros, FreeBSD, Fuchsia, gVisor, Linux, NetBSD, OpenBSD, Windows.

Mailing list: syzkaller@googlegroups.com (join on web or by email).

Found bugs: Akaros, Darwin/XNU, FreeBSD, Linux, NetBSD, OpenBSD, Windows.

Documentation

Initially, syzkaller was developed with Linux kernel fuzzing in mind, but now it's being extended to support other OS kernels as well. Most of the documentation at this moment is related to the Linux kernel. For other OS kernels check: Akaros, Darwin/XNU, FreeBSD, Fuchsia, NetBSD, OpenBSD, Windows, gVisor.
