I have heard that too however given the Meltdown flaws which people laughed at when a 1986 design review hypothesised that they would become a problem in the future and it turned out true. If it is a hatchet job then fair enough but my concern is with multiple hacking conference speakers talking about firmware vulnerabilities and mathematical backdoors in encryption technologies currently available this type of issue tends to make sense.
“Except that’s not what actually happened. Few reputable publications have questioned the existence of the flaws themselves, particularly when Dan Guido of TrailofBits declared that he’d validated and confirmed that all 13 exist.”
I think they are only the scratching the surface. These issues make sense from a logical point of view. Especially when it comes to competition between markets that cost cutting would cause testing to suffer.
Also an issue that Linus never seems to understand that bugs that require admin access are perfect for long term infiltration and are extremely useful for attacking enterprise servers as well as banks and such forth. Being able to use them allows to bypass significant counter measures to prevent intrusions. Having admin access is only part of the ball game having as many bugs as possible at every level helps.
Anyways I could be wrong.
