Of my saturdaymorning brain understands this correctly you might in fact be right https://www.gnu.org/licenses/gpl-faq.html#GPLStaticVsDynamic
Edit: however: https://www.reddit.com/r/linuxquestions/comments/1hdwm04/comment/m1zmt9d/ and https://docs.kernel.org/process/license-rules.html#id1
So I feel like this is definitely still possible and 'legal' depending on the implementation. Nvidia and AMD have done it for years.
IANAL though :p
