Webmanagement unit (MMU) of modern processors. Our AnC attack relies on the property that the MMU’s page-table walks result in caching page-table pages in the shared last-level cache (LLC). As a result, an attacker can derandomize virtual addresses of a victim’s code and data by locating the cache lines that store the WebNov 14, 2016 · A computer’s memory management unit (MMU) is the physical hardware that handles its virtual memory and caching operations. The MMU is usually located within the computer’s central processing unit (CPU), but sometimes operates in a separate integrated chip (IC).
