Re: Is Intel guilty of negligence?
Except we know that's not true. Both Arm and AMD are vunerable too albeit to a lesser extent. Which means there are at least genuinely novel and unforeseen aspects of these vunerabilities.
Unless Intel did nothing for 6 months I'm not sure they deserve ambulance chasing. I rather suspect the back channels between the chip designers have been running hot for the last 6 months.
These flaws are so severe that a reasonable case for secrecy can be made as long as those who needed to know (OS designers mostly) were kept informed.
