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.
