Data races in ticketed_lock
🔗 CVE IDs covered (1)
📋 Description
Affected versions of this crate unconditionally implemented Send for ReadTicket & WriteTicket. This allows to send non-Send T to other threads. This can allows creating data races by cloning types with internal mutability and sending them to other threads (as T of ReadTicket/WriteTicket). Such data races can cause memory corruption or other undefined behavior. The flaw was corrected in commit a986a93 by adding T: Send bounds to Send impls of ReadTicket/WriteTicket.
