>Which country laws does apply?

At the very least, Intel owns the copyright on this material, so sharing it is a copyright violation in any country that is a signatory to the Berne Convention or the TRIPS Agreement, which is effectively almost the entire planet.

Then you have to add Trade Secret laws on top of that, which will have slightly narrower jurisdiction but still impact a lot of countries. There are very few places on earth where you would not be facing any legal trouble whatsoever for releasing this material.
