From a corporate perspective you should be VERY worried about this, GPL is infectious, so if NVIDIA drivers are using GPL only parts of the kernel they become GPL, and because NVIDIA doesn’t offer GPL only endpoint the license applies to everything, meaning that if your company is using the NVIDIA driver in any way shape or form anything you produce becomes GPL as well. NVIDIA has enough lawyers to delay the enforcing of this, which is why they’ll never get sued, does YOUR company has enough lawyers to keep FSF at bay? If not you should be very annoyed at NVIDIA for not providing a license term for their GPL driver (and legally their driver IS GPL if it uses those endpoints).
And here’s the thing, for a home user not updating the kernel is good enough, for a company it’s not because this is a bug fix, not new implementation, NVIDIA is already in breach of license.
