How memory safety CVEs differ between Rust and C/C++

Rust's memory safety is more effective in practice than C or C++ because it treats potential vulnerabilities as library bugs, not user code bugs, unless the user explicitly uses the unsafe keyword. This approach allows Rust to scale in practice by automatically ensuring memory safety in safe Rust code, whereas C or C++ libraries can still be misused to introduce memory unsafety.
