GitHub AdvisoriesGHSA-rpxm-vmr7-5f5f
Data races in convec
Affected versions of this crate unconditionally implement Send/Sync for ConVec<T>.
This allows users to insert T that is not Send or not Sync.
This allows users to create data races by using non-Send types like Arc<Cell<_>> or Rc<_> as T in ConVec<T>. It is also possible to create data races by using types like Cell<_> or RefCell<_> as T (types that are Send but not Sync).
Such data races can lead to memory corruption.
