Summary
Data races in ticketed_lock
Details

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.

Severity ?
