VirtualBox error in the last update

There are reports of a kernel regression that is causing VirtualBox instability:

Many of the links mention Linux 5.18, but I saw instability issues with 5.15 (and others have reported issues with earlier kernel versions).

I was able to work around this issue by downgrading my linux515 and linux515-virtualbox-host-modules packages for now. (I also downgraded virtualbox but that might not have been necessary.)
