I can see exactly the same behavior in the Xanmod kernel.

The question is whether this has a simple solution or if it can simply be ignored since I have not observed any problems.

Looks like this is a known issue, but not that popular and hasn't had much attention: discuss.cachyos.org/t/getting-permission-denied-log-messages-from-multiple-services-after-kernel-upgrade-from-6-11-to-6-12/4300

After reviewing the links you posted, I for one am going to ignore these messages as they are warning level.

But since I saw that you linked this post, I'm going to provide additional information on the 6.11 and 6.12 kernels:
