APFS at least has metadata checksums to prevent that. However it does not do data checksums (weird decision...), despite being a CoW fs with snapshotting, similar to ZFS and btrfs.

They rely on hardware storing checksums and on protocol using checksums to prevent data corruption on all levels.
Everyone else does that as well and it's not a substitute for end-to-end data integrity.
