Researchers discovered 11 year-old unsoundness bugs in Rust's borrow checker, spanning issues from 2014 to 2022. These bugs could potentially allow unsound code to compile without triggering the expected borrow checker errors, violating Rust's safety guarantees.
Background
Rust's borrow checker is central to its memory safety guarantees, making it one of the language's defining features. The discovered bugs highlight the ongoing challenges in formally verifying complex type systems.
