L1DES (CacheOut) and VRS — new vulnerabilities in the microarchitectural structures of Intel CPUs.
Intel has disclosed information about two new vulnerabilities in Intel CPUs, caused by data leakage from the L1D cache (CVE-2020-0549, L1DES — L1D Eviction Sampling) and vector registers (CVE-2020-0548, VRS — Vector Register Sampling). These vulnerabilities belong to the MDS (Microarchitectural Data Sampling) class and are based on the application of side-channel analysis methods to data in microarchitectural structures. AMD […]
