GHSA-36cg-4jff-5863
No affected components available
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.
The vulnerability can be exploited over the network without needing physical access. It is difficult for an attacker to exploit this vulnerability and may require special conditions. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Exploitation activity has been observed. Apply available patches or mitigations urgently.
