"Anyone still keeping track of all the Spectre-based vulnerabilities
that were revealed to the public in 2018?
We published numerous articles on the topic already, and there is
certainly some fatigue involved when it comes to the class of
Two security researchers, Vladimir Kiriansky and Carl Waldspurger,
published information about two new Spectre-class vulnerabilities
which they named Spectre 1.1 and 1.2.(...)"

"Two security researchers have revealed details about two new
Spectre-class vulnerabilities, which they've named Spectre 1.1 and
Spectre 1.2.
Just like all the previous Meltdown and Spectre CPU bugs variations,
these two take advantage of the process of speculative execution - a
feature found in all modern CPUs (...).
Intel and ARM have publicly acknowledged that some of their CPUs are
vulnerable to Spectre 1.1.(...) Since all Spectre attacks affected AMD
CPUs, it is safe to assume that these new ones also affect AMD's
portfolio as well.
Researchers didn't release information on CPUs impacted by Spectre
1.2. No patches are available for either bugs at the moment (...)."
