Vulnerability from github – Published: 2021-08-25 20:50 – Updated: 2023-06-13 22:26

Summary

Data races in try-mutex

Details

Affected versions of this crate unconditionally implemented Sync trait for TryMutex type. This allows users to put non-Send T type in TryMutex and send it to another thread, which can cause a data race. The flaw was corrected in the 0.3.0 release by adding T: Send bound for the Sync trait implementation.

Severity ?

5.5 (Medium)
