An issue was discovered in the lock_api crate before 0.4.2 for Rust. A data race can occur because of MappedMutexGuard unsoundness.

 https://cve.radiocsirt.org/vuln/rustsec-2020-0070 RUSTSEC-2020-0070 — Some lock_api lock guard objects can cause data races 2026-10-16T21:02:45.307579+00:00

Affected: crates.io: lock_api

Affected versions of lock_api had unsound implementations of the `Send` or `Sync` traits for some guard objects, namely:

* MappedMutexGuard * MappedRwLockReadGuard * MappedRwLockWriteGuard * RwLockReadGuard * RwLockWriteGuard

These guards could allow data races through types that are not safe to `Send` across thread boundaries in safe Rust code.

This issue was fixed by changing the trait bounds on the `Mapped` guard types and removing the `Sync` trait for the `RwLock` guards.
