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.

 https://cve.radiocsirt.org/vuln/ghsa-qc84-gqf4-9926 GHSA-qc84-gqf4-9926 — crossbeam-utils Unsoundness of AtomicCell<{i,u}64> arithmetics on 32-bit targets that support Atomic{I,U}64 2026-10-06T05:38:09.193476+00:00

Affected: crates.io: crossbeam-utils

### Impact

The affected versions 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 with `Atomic{I,U}64` and `{i,u}64` have the same alignment are also not affected by this issue.

The following is a complete list of the builtin targets that may be affected. (last update: nightly-2022-02-11)

- armv7-apple-ios (tier 3) - armv7s-apple-ios (tier 3) - i386-apple-ios (tier 3) - i586-unknown-linux-gnu - i586-unknown-linux-musl - i686-apple-darwin (tier 3) - i686-linux-android - i686-unknown-freebsd - i686-unknown-haiku (tier 3) - i686-unknown-linux-gnu - i686-unknown-linux-musl - i686-unknown-netbsd (tier 3) - i686-unknown-openbsd (tier 3) - i686-wrs-vxworks (tier 3)

### Patches

This has been fixed in crossbeam-utils 0.8.7.

Affected 0.8.x releases have been yanked.

Affected: crates.io: crossbeam-utils

## Impact

Affected versions 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 with Atomic{I,U}64 and {i,u}64 have the same alignment are also not affected by this issue.
