Which new CPUs are immune to 2018’s new “Spectre class” vulnerabilities?
And which ARM-core parts are immune?
There was a flurry of articles about this back around Jan 11. And again in July and August. But very little since then.
So, forum, where are we today?
2018 saw a series of related security flaws discovered in modern CPUs, beginning with the disclosure of the Spectre and Meltdown vulnerabilities on Jan 2.
Intel announced, back on March 18, that they would have "security at the silicon level” to mitigate these vulnerabilities, starting with “8th Generation Intel Core processors expected to ship in the second half of 2018”.
But, that announcement was made before the group of “Spectre NG” vulnerabilities was published in May. Before the Intel-specific Foreshadow exploit was published in August.
And long before the first “Systematic Evaluation of Transient Execution Attacks” was published in November.
So, what have Intel, AMD, and ARM learned during the course of the year?
Do any of them have new CPUs that fully mitigate this class of attacks?
How many older CPUs now have microcode patches available?
And what was the final word on the performance penalty incurred by installing those patches?
