I’m still amazed this went on for so long without anybody noticing.

I’ve worked with embedded systems doing high performance coding and we always just assumed that once the cache path was invalidated that it was inaccessible.

Processor development has always been a “black box.” I would bet good money that as quantum computing becomes more accessible, these types of hardware exploits will become more common and easily exploitable on aging platforms.
