An issue was discovered in the signal-simple crate through 2020-11-15 for Rust. There are unconditional implementations of Send and Sync for SyncChannel<T>.

 https://cve.radiocsirt.org/vuln/rustsec-2020-0126 RUSTSEC-2020-0126 — SyncChannel<T> can move 'T: !Send' to other threads 2026-10-15T21:14:59.034584+00:00

Affected: crates.io: signal-simple

Affected versions of this crate unconditionally implement Send/Sync for `SyncChannel<T>`. `SyncChannel<T>` doesn't provide access to `&T` but merely serves as a channel that consumes and returns owned `T`.

Users can create UB in safe Rust by sending `T: !Send` to other threads with `SyncChannel::send/recv` APIs. Using `T = Arc<Cell<_>` allows to create data races (which can lead to memory corruption), and using `T = MutexGuard<T>` allows to unlock a mutex from a thread that didn't lock the mutex.
