Kernel error reports from VirtualBax

Since the update to virtualbox-ose-kmod-6.1.28, I have been seeing a very
large number of the error:
vboxdrv: Bad CPU context error at line 373 in SUPDrv-freebsd.c:
ulCmd=0x2000568a: 0x282->0x287!
hundreds of times a day.

I have seen no actual issues with my VMs. They run fine as far as I can
tell. Any idea if I need to worry about these messages? Any explanation of
what they might mean?

Running reeBSD 13.0-STABLE #0 stable/13-n247697-351cad089f2: Mon Oct 18
