Any security hardware using this oscillator would be at risk too. I can see the Mission Impossible plot to use it to attack a security systems and IP cameras if they used those chips.
I'm not sure how far this vulnerability will ever get an attacker because most devices will probably continue to use regular quarts oscillators that aren't sensitive to this like MEMS devices. Apple probably only uses them because they're squeezing every ounce of space and their markups can stand the increased cost of the MEMS vs the quartz/ceramic oscillators.
