crossbeam-utils Race Condition vulnerability
The affected version of this crate 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 the following problems: Unaligned memory accesses 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. 32-bit targets …
