Data races in rcu_cell

High severity GitHub Reviewed Published Aug 25, 2021 to the GitHub Advisory Database • Updated Feb 1, 2023

Package

cargo rcu_cell (Rust)

Affected versions

< 0.1.9

Patched versions

0.1.9

Description

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.
