Hi @hokosugi the security team has actually looked into this potential exploit (if I am not mistaken you are referring to the same exploit, correct me if I am wrong), and assessed that for the IC this risk is limited: see this forum post How to check if Node Machines are GEN1 or GEN2 - #2 by SvenF.
By the way many thanks for the note as it is important that we need to keep reviewing potential exploits based on the hardware specification!
