Found bugs: [Darwin/XNU](docs/darwin/README.md), [FreeBSD](docs/freebsd/found_bugs.md), [Linux](docs/linux/found_bugs.md), [NetBSD](docs/netbsd/found_bugs.md), [OpenBSD](docs/openbsd/found_bugs.md), [Windows](docs/windows/README.md).

## 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](docs/linux/setup.md) kernel.
