Security risk installing Virtualbox guest utils/dkms to build kernel modules?

[lynda]

When installing this VirtualBox Guest Additions on a Xubuntu linux guest VM, I received the following message:

VirtualBox Guest Additions: Building the modules for kernel 6.5.0=15-generic.
This system is currently not set up to build kernel modules.
Please install the gcc make perl packages from your distribution.

It is my understanding I need to install:
virtualbox-guest-utils
virtualbox-guest-dkms <-- Package wasn't found for my distribution. Need dkms instead.
dkms

I do not know what installing the above packages will do, but my main question:
Is there a security risk installing Virtualbox utils/dkms to build/manipulate kernel modules?

Official Guest Additions from www.virtualbox.org have prerequisites in Linux, same as Official Virtualbox on the host, see https://www.virtualbox.org/manual/ch04. ... ions-linux and https://www.virtualbox.org/manual/ch02. ... nux-prereq

However, neither Official GAs nor Official Virtualbox require dkms. The Linux forks of GAs and Virtualbox may, though.

If you're using the forks from the Linux distro repositories, you'll have to ask the distro help channels about dkms. If you are using Official, you don't need dkms.
