Oh, probably at least a year… So even with motivation and time AND all the information presented right there in front of you, it can take a while. THIS bug apparently involves doing stuff that isn’t really supposed to work.<o:p></o:p></span></p>

<br>
In a nutshell, it is a major security flaw in Intel hardware dating back a decade that is requiring a complete kernel rewrite for every major OS (Linux, Windows, Mac, etc) in order to patch out. It cannot be patched out with a CPU microcode update. Major enough
that code comments are redacted in the patches until an embargo period is expired. Also the reported fix will have a huge performance impact.<br>
<br>
Also crucial to note is that AMD chips are not affected by this.<br>
<br>
How the heck does something like this go unnoticed for so long?<br>
