AddressSanitizer (ASan)

AddressSanitizer (ASan) is a powerful memory error detector that instruments code at compile-time to identify critical vulnerabilities such as buffer overflows, use-after-free bugs, and memory leaks. By mapping virtual memory to track allocation states, it provides developers with detailed stack traces and error reports during fuzzing or unit testing. It is an essential tool for securing low-level codebases where manual memory management often leads to exploitable security flaws, offering a robust way to ensure memory safety before deployment.
