Summary
- Detects buffer overflows, use-after-free, double-free, and memory leaks by instrumenting code at compile time with the -fsanitize=address flag
- Requires approximately 20TB of virtual memory; disable fuzzer memory limits with -rss_limit_mb=0 (libFuzzer) or -m none (AFL++)
- Introduces 2–4x performance overhead; best suited for testing and fuzzing, not production use
- Integrates with libFuzzer, AFL++, cargo-fuzz, and honggfuzz; configure via ASAN_OPTIONS environment variable for verbosity, leak detection, and error handling behavior
