Each of the eight vulnerabilities has its own number in the Common Vulnerability Enumerator (CVE) directory and each requires its own patches. It is likely that each vulnerability will receive its own name. Until then, we will jointly call these flaws Spectre-NG in order to distinguish them from the previously uncovered issues.

So far we only have concrete information on Intel’s processors and their plans for patches. However, there is initial evidence that at least some ARM CPUs are also vulnerable. Further research is already underway on whether the closely related AMD processor architecture is also susceptible to the individual Spectre-NG gaps, and to what extent.

ARM keeps looking better and better, even though it’s not perfect either. I have a hard time thinking Intel is taking this seriously enough.
