Vulnerability from variot

Page table walks conducted by the MMU during virtual to physical address translation leave a trace in the last level cache of modern ARM processors. By performing a side-channel attack on the MMU operations, it is possible to leak data and code pointers from JavaScript, breaking ASLR. ARM Cortex A53 and so on are CPU processors of British ARM company.

There are security vulnerabilities in many ARM processors. Attackers can exploit this issue to bypass certain security restrictions and perform unauthorized actions. Little is known about this issue or its effects at this time. We will update this BID as more information emerges
