A soundness issue was discovered in tokio. tokio::io::ReadHalf::unsplit can violate the Pin contract. Specific set of conditions needed to trigger an issue (a !Unpin type in ReadHalf) is unusual, combined with the difficulty of making any arbitrary use-after-free exploitable in Rust without doing a lot of careful alignment of data types in the surrounding code. The tokio feature io-util is also required to be enabled to trigger this soundness issue.
