Rust is popular because it lends itself more easily to writing secure software. Samartha Chandrashekar, an AWS Product Manager, said it “helps ensure thread safety and prevent memory-related errors, such as buffer overflows that can lead to security vulnerabilities.” Many other developers agree with Chandrashekar.
In Linux circles, Alex Gaynor and Geoffrey Thomas at the 2019 Linux Security Summit said that about two-thirds of Linux kernel vulnerabilities come from memory safety issues. Rust, in theory, can completely avoid these by using Rust’s inherently safer application programmer interfaces (API)s.
