mariadb/galera 10.3.27 crashes during certain queries

Hello, we experienced multiple mariadb/galera crashes in the mentioned environment.

After googling around I think we hit this bug, but I'm not 100% sure as I'm not familiar with the sourcecode of galera nor mariadb:

MDEV-23851

So I figured I create a separate bugreport, in case it is something else (maybe related?).

Jira does not let me attach the file (I always get an error), so here's a link to the log:
https://drive.google.com/file/d/1B3EpKL2R4lgB-NOzvnzxd4zhzQqUl4lF/view?usp=sharing

You can easily find the crash by searching for "assertion".

If you need any other/more information regarding these crashes, please don't hesitate to contact me here or via email.

If this is indeed the same bug as MDEV-23851 may I kindly ask if there is any timeline when the fix in 10.3.28 will be released? Even a raw estimate would be really helpful, because we must decide if it is worthwile to rollback to a more stable release.

For reference (maybe others hit this bug as well):

This occurred in a pre production openstack environment during setup of kubernetes clusters via the "magnum" project of openstack.

We were also able to sometimes reproduce this issue in our virtual test environment during cluster creation, specifically during network setup for the cluster, so it seems magnum is able to produce the relevant queries to make galera/mariadb crash.
