Computer scientists from imec-DistriNet (KU Leuven), the University of Birmingham, and TU Graz have shown that the possibility to adjust the operating voltage of Intel processors makes them vulnerable to attack. 

Modern processors are being pushed to perform faster than ever before, and with this come increases in heat and power consumption. That is why many chip manufacturers allow for frequency and voltage to be adjusted as and when needed - known as ’undervolting’ or ’overvolting’ - through what is known as privileged software interfaces. ...
