When creating frame buffer, userspace may request to attach to a previously allocated GEM object that is smaller than what GPU requires. Validation must be done to prevent out-of-bound DMA, otherwise it could be exploited to reveal sensitive data. This fix is not done in a common code path because individual driver might have different requirement.
