- Summary
- Data races in conquer-once
- Details
-
Affected versions of conquer-once implements Sync for its OnceCell type without restricting it to Sendable types.
This allows non-Send but Sync types such as MutexGuard to be sent across threads leading to undefined behavior and memory corruption in concurrent programs.
The issue was fixed by adding a Send constraint to OnceCell.
