VirtualBox is not a Fedora Package and the kernel modules are not maintain by Fedora, so each time you run dnf update and the kernel gets updated you need to compile the VirtualBox kernel module. You have two options there to compile it or run Fedora with the Kernel Version that was working before. Best option is to use kvm virtualization which is native on Fedora and use Virtual-manager to manage.

There should be an akmod for VirtualBox. This way VB kernel module is rebuilt when you reboot.

No need to recompile kernel modules manually if you have dkms installed (also requires kernel-headers, kernel-devel, and maybe others). Search this site - this questions has been asked and answered many times. You need to installed dkms before installing VirtualBox so that the modules get registered correctly with dkms.

I'd recommend installing VirtualBox from rpmfusion. It drags in all the needed kernel mods and then all you need to do after an upgrade is restart to allow the new kernel mods to install.

Same happening when using dkms
