Intel, Microsoft, and Mozilla, meanwhile, downplayed the issue. “We've determined it does not represent a security issue," says a statement Microsoft PR emailed to WIRED. Intel writes that the research "doesn't represent a significant change in the security of Intel Architecture–based systems." Spokespeople from all three companies point out that the attack alone only represents a threat in combination with another memory corruption bug. Samsung, Nvidia, AMD, and Google didn't respond to WIRED's request for comment.
