Rust Kernel Bugs

1. Brief critique and context: Rust is designed to provide memory safety and prevent common vulnerabilities such as buffer overflows and use-after-free errors, which are prevalent in languages like C and C++. However, Rust's guarantees primarily address memory safety, not logic errors or other classes of vulnerabilities. Kernel-level programming introduces additional complexities, such as concurrency and hardware interactions, which may not be fully mitigated by Rust's memory safety features alone.

2. Recent research: A relevant study is "RustBelt: Securing the Foundations of the Rust Programming Language" (https://dl.acm.org/doi/10.1145/3133956). The study formalizes aspects of Rust's type system and safety guarantees but acknowledges that while Rust addresses certain classes of vulnerabilities, it does not eliminate all potential security issues. Additionally, research on the Linux kernel's integration of Rust (https://lwn.net/Articles/839858/) highlights ongoing efforts to assess Rust's impact on kernel security but does not yet provide comprehensive field data on large-scale deployments.

3. Bayesian likelihood of falsification: 40%. While Rust's memory safety features significantly reduce certain types of vulnerabilities, kernel-level programming poses unique challenges beyond memory safety, such as race conditions and logic errors. Given the complexity of kernel code and the nascent state of Rust in this domain, it is plausible that critical vulnerabilities could still occur. However, as Rust adoption and tooling improve, the likelihood of achieving the conjecture's falsification criteria within five years remains uncertain but possible.
