Summary
CVE-2022-23639 affecting package rust for versions less than crossbeam_utils-0.8.7
Details

crossbeam-utils provides atomics, synchronization primitives, scoped threads, and other utilities for concurrent programming in Rust. crossbeam-utils prior to version 0.8.7 incorrectly assumed that the alignment of {i,u}64 was always the same as Atomic{I,U}64. However, the alignment of {i,u}64 on a 32-bit target can be smaller than Atomic{I,U}64. This can cause unaligned memory accesses and data race. Crates using fetch_* methods with AtomicCell<{i,u}64> are affected by this issue. 32-bit targets without Atomic{I,U}64 and 64-bit targets are not affected by this issue. This has been fixed in crossbeam-utils 0.8.7. There are currently no known workarounds.
