An issue was discovered in the rcu_cell crate through 2020-11-14 for Rust. There are unconditional implementations of Send and Sync for RcuCell<T>.

GHSA-686h-j8r8-wmfm — Data races in rcu_cell

Affected: crates.io: rcu_cell

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.

RUSTSEC-2020-0131 — Send/Sync bound needed on T for Send/Sync impl of RcuCell

Affected: crates.io: rcu_cell

This can result in memory corruption caused by data races.
