 A recent example of how fuzzing helps spot a vulnerability in an open-source project is [CVE-2022-0185](https://www.openwall.com/lists/oss-security/2022/01/18/7): a Linux 0-day found by the Crusaders of Rust a few weeks ago. It was discovered using the [syzkaller](https://github.com/google/syzkaller) kernel fuzzer. The process was documented on Will's Root:

 I _highly_ encourage giving it a read; it's the perfect example of fuzzing with sanitizers to find a vulnerability, reproducing the vulnerability (by writing a tiny C program), _then_ diving into the source code to find and fix the cause, and finally reporting the issue (with a patch!). When source isn't available, the vendor would assume responsibility for the "find and fix" steps.
