I'm using 5.15, which is affected, and someone on the vbox forum mentioned that 5.10 is affected. Don't know about any kernels further back.
Currently it seems that the solution is to downgrade kernel minor version and/or downgrade vbox to 6.1.32; don't know if I need to do both or if only one is enough.
Fedora people report that vbox 6.1.35 test version works, so I would rather run that, but don't know (or have time to figure out) how to convert the .run file to an Arch/AUR package. (Don't know if that's even necessary; will have a look, see if its contents can run from a manual placement.)
I don't understand all the details -- just an end-user who needs to do a bit of work in Win11. ;)

Notice:
To avoid crashes when upgrading Guest Additions from version 6.x to 7.x on Windows guests, uninstall the old Guest Additions first, then reboot, and then install the new ones. It's recommended to do all these operations in Safe Mode. See this upstream bug ticket for more details.
