Hello guys,
Doing usual checking activities today I came across this warning:

Is there anything I can do to fix it?
In essence is it a problem at all?

Ups forgot to mention that I see this only on latest kernel versions like the one blow:

5.15.35-2-pve
5.15.35-3-pve

I have switched to 5.13.19-6-pve - no issues at all.
