https://safirsoft.com Similar Meltdown Vulnerability Revealed for AMD Zen+ and Zen 2 . Processors

AMD, along with security researchers at the Dresden University of Technology, has uncovered a vulnerability in some AMD processors similar to the Meltdown and Specter vulnerabilities in Intel processors disclosed three years ago. AMD has already introduced several mitigation technologies to combat these vulnerabilities.

Researchers at TU Dresden, Saeedgani Musif and Christoph Fetzer, have warned AMD of abuses in Zen+ and Zen 2 processors, which they describe as "unconventional access transient execution" and are directly compared to Specter and Meltdown. The AMD Security Bulletin mentions a vulnerability called CVE-2020-12965.

AMD says the main risk is that it could cause unimaginable CPU leaks. "In combination with specific software sequences, AMD CPUs may transiently execute unconventional loads and may leak data using only 48 bits below the address." A research paper from AMD followed this up with a special review published in the Bulletin. On the same page, AMD also has a document that explains how to downgrade it. AMD wrote: “There are different types of software that can be used to manage operations management, each with different features and parameters.

AMD advises developers to browse their code running on defective processors and enter LFENCE or use one. It has more security features to protect against such vulnerabilities, such as SMEP, SMAP and IBC.Access was exposed, while Specter can be used to execute malicious code, and fix these vulnerabilities that initially caused performance crashes that were eventually reduced, Such as Meltdown, which can be used to leak data. Violations must be protected.
