About

syzkaller is an unsupervised coverage-guided kernel fuzzer designed to automatically find bugs in various OS kernels.

syzkaller is an unsupervised coverage-guided kernel fuzzer

Primary Use Case

This tool is primarily used by kernel developers and security researchers to automatically discover vulnerabilities and bugs in operating system kernels such as Linux, Windows, and BSD variants. It helps improve kernel security by fuzz testing kernel interfaces without manual supervision, enabling early detection of critical security flaws.

Key Features

Unsupervised coverage-guided fuzzing of OS kernels
Supports multiple operating systems including Linux, Windows, FreeBSD, NetBSD, OpenBSD, Fuchsia, gVisor, and more
Extensive documentation and found bugs reports for various OS kernels
Integration with syzbot for automated bug reporting and triaging
Open source with active CI and code coverage monitoring
Written in Go with comprehensive GoDoc documentation
Apache 2.0 licensed

Installation

Refer to the installation guide at docs/setup.md for detailed setup instructions
Clone the repository from https://github.com/google/syzkaller
Follow OS-specific setup guides for supported kernels (e.g., docs/linux/setup.md for Linux)
Set up syzbot for automated fuzzing and bug reporting using docs/setup_syzbot.md
Ensure Go environment is configured as syzkaller is written in Go
