syzkaller - kernel fuzzer

syzkaller is an unsupervised coverage-guided kernel fuzzer. Linux kernel fuzzing has the most support, akaros, freebsd, fuchsia, netbsd, windows and gvisor are supported to varying degrees.

The project mailing list is syzkaller@googlegroups.com. You can subscribe to it with a google account or by sending an email to syzkaller+subscribe@googlegroups.com.

List of found bugs.

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.
