Vulnerability from github – Published: 2021-08-25 20:59 – Updated: 2021-08-24 18:24

Summary
Data races in convec
Details

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.

Severity
8.1 (High)
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
