Masterkey, according to CTS-Labs, allows the injection of persistent malware into the Secure Processor, among other attacks.
While the vulnerabilities all require administrator access before they can be exploited, making them significantly more hard for intruders to use, they are risky in that they allow complete access to the system, including secure processing areas normally off-limits to malware.
The flaws were uncovered by Israeli security firm CTS-Labs, which noted that the vulnerabilities affect the Secure Processor, a co-processor found on AMD's CPUs where sensitive data such as encryption keys and passwords are stored.
The second, dubbed Ryzenfall, consists of four "design and implementation flaws" inside the AMD Secure OS, which powers the AMD Secure Processor found in Ryzen, Ryzen Pro and Ryzen Mobile products.
"You're virtually undetectable when you're sitting in the secure processor", Luk-Zilberman said of the flaws. CTS-Labs claims it's been able to exploit the vulnerabilities it found on several Ryzen chips, but no potential attack has been seen in the wild.
Fallout exposes the bootloader within the Epyc Secure Processor, allowing access to protected memory regions, CTS-Labs claims. It's also worth noting that AMD has been made aware of the issues, as have "select security companies" that could help mitigate the fallout and USA regulators. CTS-Labs blamed ASMedia, a third-party chipmaker that supplied the USB host controller and SATA controller within AMD's Ryzen chipset, for these vulnerabilities, which were then introduced into the Ryzen chipsets.
"CTS believes that networks that contain AMD computers are at a considerable risk", the report said. "The vulnerabilities we have discovered allow bad actors who infiltrated the network to persist in it, surviving computer reboots and reinstallations of the operating system, while remaining virtually undetectable by most endpoint security solutions", the advisory said. We are actively investigating and analyzing its findings. However, the outfit gave AMD a week to come up with a fix before it went public.
Investment firm Viceroy Research published a 25-page report on the issues after the company said it was anonymously emailed a copy of CTS' findings on Monday afternoon.
AMD confirmed it's been made aware of the potential vulnerabilities.
An AMD spokesperson told CNET it is investigating the report, which they "just received".
"At AMD, security is a top priority and we are continually working to ensure the safety of our users as new risks arise", the California-based company said in a statement.
We will update this story when more information is available.
As with the Spectre and Meltdown vulnerabilities, it will take time for the true nature of the risk to become clear, but already security commentators appear to be divided in their opinion.
This could allow attackers "to inject malicious code into the chip" and create "an ideal target" for hackers, the researchers said.
