Details

As written in the advisory (Markdown source, shown as plain text).

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.
