Why it matters #
Rust is being adopted for foundational software on the promise that safe code cannot cause memory-safety failures. Microsoft's reproduced stdlib findings show where that promise depends on unsafe code, and why AI tools that understand operating-system behavior may expand the search space for soundness bugs.
Microsoft's FORGE Lab said on November 9th that it found several memory-safety issues in Rust's core and std libraries, including cases where code written entirely in safe Rust can trigger undefined behavior.…
