Microsoft has released a new batch of Intel microcode updates for Windows 10 20H2, 2004, 1909, and older versions to fix new hardware vulnerabilities discovered in Intel CPUs. Today, an international group of researchers from Graz University of Technology, CISPA Helmholtz Center for Information Security, and the University of Birmingham disclosed new Intel CPU side-channel vulnerabilities called Platypus. These vulnerabilities reside in Intel’s Running Average Power Limit (RAPL) interface, allowing users to monitor and manage the power consumption of supported CPUs and DRAM memory.
