Arch devs,
Not real sure where to send this, but there were issues discovered
with Virtualbox and the 6.18 kernel by the openSUSE virtualbox
maintainer (Jan Engelhardt). I thought I would pass this along while
6.18 remains in testing with Arch to confirm the issue.

Subject: Virtualbox VMM corruption with 6.18

This is just an informational mail from your virtualbox package maintainer.
I have observed that VirtualBox 7.2.4, which has basically been rolled
out in August 2025 and worked just fine, to start showing guest memory
corruption in December. Compilers would randomly fail in both OpenBSD
and Solaris. Likewise, package installation when running the Leap 15.6
installer ISO would randomly fail. The only thing that changed in that
timeframe was the host kernel in Tumbleweed, namely from 6.17 to 6.18.
I have already tried applying a vbox patch (e7db388f) from their Git
which mentioned corruption, but without positive remedy.
So for now, please take note you cannot realistically use VB 7.2.4
with a host kernel version >=6.18. The workaround, for me anyway,
is using an older host kernel like 6.17.11.
