Intel Fixes Dangerous Plundervolt Vulnerability

December 13, 2019

Intel has quickly released a fix for the new and already infamous Plundervolt vulnerability found in Intel 6th, 7th, 8th, 9th, and 10th generation processors, alongside Xeon Processor E3 v5 and v6, and Xeon Processor E-2100 and E-2200.

Security researchers identified a vulnerability in Intel Software Guard Extensions (Intel SGX), which is a piece of architecture embedded in several Intel processors that allows users (including the OS) to store essential code in protected enclaves, akin to a vault. Attackers obtained the cryptography key for the encrypted SGX data by lowering the voltage, compromising any system.
