 |  Scary new bug hits ARM Brilliant and Terrifying Columbia University researchers have found a “brilliant and terrifying” hack of ARM chips using something they call CLKSCREW. The hack targets ARM’s Dynamic Voltage and Frequency Scaling (DVFS), which allows the CPU's clockspeed and voltage to vary dynamically depending on whether the CPU is idling or not. CPU or SoC chipset vendors embed energy management systems with their products to allow device manufacturers a way to control energy consumption and improve battery life. http://fudzilla.com/news/44577-scary-new-bug-hits-arm |
