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, or Stealer::steal_batch_and_pop are affected by this issue.

Patches

This has been fixed in crossbeam-deque 0.8.1 and 0.7.4.

Credits

This issue was reported and fixed by Maor Kleinberger.
