Vulnerability from github – Published: 2021-08-25 20:57 – Updated: 2021-08-24 17:53
VLAI?
Summary
Data races in rcu_cell
Details

Affected versions of this crate unconditionally implement Send/Sync for RcuCell<T>. This allows users to send T: !Send to other threads (while T enclosed within RcuCell<T>), and allows users to concurrently access T: !Sync by using the APIs of RcuCell<T> that provide access to &T.

This can result in memory corruption caused by data races.

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