CVE-2020-36461 — Vulnerability in noise_search — CVE Details

HIGH

MvccRwLock allows data races & aliasing violations

Published December 10, 2020Updated November 8, 2023Source: osv

Summary

Affected versions of this crate unconditionally implement 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). Also, safe APIs of `MvccRwLock` allow aliasing violations by allowing `&T` and `LockResult<MutexGuard<Box<T>>>` to co-exist in conflicting lifetime regions. The APIs of `MvccRwLock` should either be marked as `unsafe` or `MbccRwLock` should be changed to private or pub(crate).
