How a named pipe I/O race condition happens in Rust mio and how to fix it

CVE-2024-27308 is a high-severity vulnerability in the Rust `mio` crate (versions prior to 0.8.11) that exposes a race condition in named pipe I/O event handling on Windows. The fix upgrades `mio` from version 0.8.10 to 0.8.11, closing the window for potential exploitation in applications like `rpm-ostree` that depend on async I/O. Because `mio` sits at the foundation of the Tokio async runtime, this flaw has wide blast radius across the Rust ecosystem.
