"AMD Processors Susceptible to Security Vulnerabilities, Data Leaks"
Researchers at Graz University of Technology discovered that AMD CPU microarchitectures from 2011 to 2019 are vulnerable to side-channel attacks. In a paper, titled "Take A Way: Exploring the Security Implications of AMD's Cache Way Predictors," the researchers discuss the demonstration of two new attack techniques, called "Collide + Probe" and "Load + Reload." These techniques exploit vulnerabilities in AMD's LD1 cache way predictor, which is designed to predict where data is stored in the processor and determine when the data is accessed. Using the techniques, an attacker could access AES encryption keys. This article continues to discuss the AMD CPU infiltration approaches demonstrated by researchers and how the weaknesses exploited to perform these attacks could be addressed.
