I received this error for
5.10.10-200.fc33.x86_64 after rebooting:
A kernel problem occurred, but your kernel has been tainted (flags:GOE). Explanation:
O - Out-of-tree module has been loaded.
E - Unsigned module has been loaded.
Kernel maintainers are unable to diagnose tainted reports. Tainted modules: vboxnetadp ,vboxnetflt and vboxdrv.
vboxnetadp,vboxnetflt and vboxdrv are Virtualbox modules (which I have installed and use actively).

I’m aware that at least a decade ago the VB driver was considered as poor by the Linux kernel maintainers.
