HIGH

Data race in v9

Published August 25, 2021Updated November 8, 2023Source: osv

Summary

Affected versions of this crate unconditionally implement Sync for SyncRef<T>. This definition allows data races if &T is accessible through &SyncRef. SyncRef<T> derives Clone and Debug, and the default implementations of those traits access &T by invoking T::clone() & T::fmt(). It is possible to create data races & undefined behavior by concurrently invoking SyncRef<T>::clone() or SyncRef<T>::fmt() from multiple threads with T: !Sync.
