ARM – Majority Of Our Processors Are Not Impacted
ARM Holdings – which makes processors for smartphones- said the "majority of ARM processors" are not impacted by Spectre and Meltdown.
That said ARM cautioned users that it is important to note that the exploits are dependent on "malware running locally which means it's imperative for users to practice good security hygiene by keeping their software up-to-date and avoid suspicious links or downloads."
ARM said the "cache timing side-channels" involved in the exploits are a well-understood concept in the area of security research and is not a new finding. "However, this side-channel mechanism could enable someone to potentially extract some information that otherwise would not be accessible to software from processors that are performing as designed," the company said.
