AMD Security Announcement on Fallout, RIDL and ZombieLoad Attack

AMD today responded to yesterday's news about the new serious Intel processor vulnerabilities. In this announcement, they confirmed that their processors are not susceptible to this kind of vulnerability.

Yesterday, researchers announced three new security exploits – Fallout, Rogue In-Flight Data Load (RIDL) and “ZombieLoad Attack”. Based on our internal assessment, we believe AMD products are not impacted by these new threats.

Below is our public statement, which you’ll also find available here.

At AMD we develop our products and services with security in mind. Based on our analysis and discussions with the researchers, we believe our products are not susceptible to ‘Fallout’, ‘RIDL’ or ‘ZombieLoad Attack’ because of the hardware protection checks in our architecture. We have not been able to demonstrate these exploits on AMD products and are unaware of others having done so.

You can read up all about it in this whitepaper, titled “Speculation Behavior in AMD Micro-Architectures.”
