If I wasn't clear, I'm asking about vulnerabilities in the baseband processor (BBP), not the CPU. The BBP is what makes a smartphone a phone, rather than a small tablet: https://en.m.wikipedia.org/wiki/Baseband_processor https://en.m.wikipedia.org/wiki/Baseband_processor The thing about the BBP is that it is a second computer running its own proprietary OS (typically an RTOS) to handle the RF modem. The phone's main OS typically has no visibility into that second computer, even as root, but the reverse may not be true. So I was wondering if any of Google's efforts to increase security can mitigate attacks that might come through this particular channel that lurks, Kuato like, just out of sight.
