[$] Fuzzing perf_events
You might be surprised to learn that starting with Linux 2.6.31 (in 2009) it has been rather easy to crash the Linux kernel. This date marks the introduction of the perf_event subsystem. It is likely that perf_event is not any more prone to errors than any other large kernel subsystem, but it has the distinction of being subjected to intense testing from the perf_fuzzer tool, which methodically probes the interface for bugs.
