The key length for encrypted devices created using ceph-volume is
incorrect. This is due to a bug in ceph_volume/util/encryption.py, where
upon writing a key using osd_dmcrypt_key_size it does not pass the key size
to the format and open operations following. The default key is then
applied in cryptsetup. All versions since Luminous are assumed affected."
Doesn't seem there's any patch at URL and don't see any report upstream.
Possible patch (seems unupstreamed): https://www.openwall.com/lists/oss-security/2022/01/11/5
Might cause data corruption, though: https://www.openwall.com/lists/oss-security/2022/01/12/1
