8.1 (High) CVSS_V3 - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H CVSS Calculator

Summary

`LockWeak<T>` allows to create data race to `T`.

Details

In the affected versions of this crate, LockWeak<T> unconditionally implemented Send with no trait bounds on T. LockWeak<T> doesn't own T and only provides &T.

This allows concurrent access to a non-Sync T, which can cause undefined behavior like data races.
