Re: ARM or Apple?

My guess is that IoT SoCs won't be affected by this as they're almost always using older ISA versions and with limited focus on CPU speed, instead focusing either on power consumption or acceleration for specific tasks like network comms or video encoding. Server chips probably aren't seeing this for now because a lot of the ARM designs are older and many companies trying them have given up on getting users over to them, but if they come back with new designs, it should be tested. I wouldn't be surprised to hear that some modern smartphone chips have this vulnerability as well, but likely the researchers would have to redesign their test binary to run it on Android (and running on IOS would likely be a bit more painful) so they've started here. Investigating those might be step 2 of the project, or they might go and look for new exploits and let a different research team test more hardware with their code.
