This page provides download links to important resources, such as whitepapers and mitigation specifications, related to the Arm processor security update. 

Cache Speculation Side-channels Whitepaper

This whitepaper looks at the susceptibility of Arm implementations following recent research findings from security researchers at Google on new potential cache timing side-channels exploiting processor speculation. This paper also outlines possible mitigations that can be employed for software designed to run on existing Arm processors.


Firmware interfaces for mitigating CVE-2017-5715 System Software on Arm Systems

This specification defines additional services that should be provided by firmware on systems with affected CPUs which enables operating system and hypervisor software to apply appropriate workarounds for CVE-2017-5715, and to discover the presence of this firmware service.
