This ticket is a duplicate of #21690. Fix is now available with the test builds.

As my search for "drm_framebuffer" and/or "vbox_drv.h" lead me to this ticket, just to append: had the same issue in RHEL 8.6 for those kernels:
4.18.0-477.13.1.el8_8.x86_64
4.18.0-477.15.1.el8_8.x86_64

I did as #21690 advises and installed VBoxGuestAdditions_6.1.45-158226 today with success: "/sbin/rcvboxadd quicksetup all" works without errors.
