Rowhammer rapidly flips bits in RAM. The bits that are rapidly flipped are chosen for their proximity to the physical transistors which store the UID. By flipping the bit near the transistors storing the UID very quickly, it's possible to induce a bit flips in the UID value itself and gain root access. This is a flaw inherent to DRAM, and it completely OS independent. It's a hardware level exploit.
- pbhjpbhj 10y agoWow, first I've heard of that one - someones a smart cookie to come up with that, props.
- baq 10y agothe comments here say that engineers who were developing first DRAMs knew about this since the very beginning and there are actually qualification tests for the hardware. the problem is that capacities got too large to test effectively.
- ommunist 10y agoThank you for the explanation. But will it not disable automatic updates, and AppStore functionality, since UID will loose its integrity?
