Rook users are seeing OSDs fail on arm64 with v18.2.4. I would think it also affects non-rook users.

We're happy to announce the 4th release in the Reef series.
An early build of this release was accidentally exposed and packaged
as 18.2.3 by the Debian project in April. That 18.2.3 release should
not be used. The official release was re-tagged as v18.2.4 to avoid
further confusion.
v18.2.4 container images, now based on CentOS 9, may be incompatible
on older kernels (e.g., Ubuntu 18.04) due to differences in thread
creation methods. Users upgrading to v18.2.4 container images with
older OS versions
may encounter crashes during `pthread_create`. For workarounds, refer
to the related tracker. However, we recommend upgrading your OS to
avoid this unsupported combination.

We recommend users to update to this release.

Notable Changes
---------------
* RADOS: This release fixes a bug (https://tracker.ceph.com/issues/61948) where
pre-reef clients were allowed to connect to the `pg-upmap-primary`
(https://docs.ceph.com/en/reef/rados/operations/read-balancer/)
interface despite users having set `require-min-compat-client=reef`,
leading to an assert in the osds and mons. You are susceptible to this
bug in reef versions prior to 18.2.3 if 1) you are using an osdmap
generated via the offline osdmaptool with the `--read` option or 2)
you have explicitly generated pg-upmap-primary mappings with the CLI
command. Please note that the fix is minimal and does not address corner
cases such as adding a mapping in the middle of an upgrade or in a partially
upgraded cluster (related trackers linked in
https://tracker.ceph.com/issues/61948).
As such, we recommend removing any existing pg-upmap-primary
mappings until remaining
issues are addressed in future point releases.
See https://tracker.ceph.com/issues/61948#note-32 for instructions
on how to remove
existing pg-upmap-primary mappings.
* RBD: When diffing against the beginning of time (`fromsnapname == NULL`) in
fast-diff mode (`whole_object == true` with `fast-diff` image feature enabled
and valid), diff-iterate is now guaranteed to execute locally if exclusive
lock is available. This brings a dramatic performance improvement for QEMU
live disk synchronization and backup use cases.
* RADOS: `get_pool_is_selfmanaged_snaps_mode` C++ API has been deprecated
due to being prone to false negative results. It's safer replacement is
`pool_is_in_selfmanaged_snaps_mode`.
* RBD: The option ``--image-id`` has been added to `rbd children` CLI command,
so it can be run for images in the trash.
