WS-2020-0281
Date: August 19, 2025
noise_search crate through 0.7.0 unconditionally implements Send/Sync for MvccRwLock. This can lead to data races when types that are either !Send or !Sync (e.g. Rc<T>, Arc<Cell<_>>) are contained inside MvccRwLock and sent across thread boundaries. The data races can potentially lead to memory corruption (as demonstrated in the PoC from the original report issue).
