- Summary
- crossbeam-deque Data Race before v0.7.4 and v0.8.1
- Details
-
Impact
In the affected version of this crate, the result of the race condition is that one or more tasks in the worker queue can be popped twice instead of other tasks that are forgotten and never popped. If tasks are allocated on the heap, this can cause double free and a memory leak. If not, this still can cause a logical bug.
Crates using
Stealer::steal,Stealer::steal_batch, orStealer::steal_batch_and_popare affected by this issue.Patches
This has been fixed in crossbeam-deque 0.8.1 and 0.7.4.
