Apple’s silicon has just been discovered by researchers with a new vulnerability called “Augury”. But for now, they don’t seem to be overly concerned about that.
Researchers Michael Flanders of the University of Washington and Jose Rodrigo Sanchez Vicarte of the University of Illinois at Urbana-Champaign published their findings here. As reported by Digital Trends, the two discovered that the vulnerability stems from Apple’s problematic implementation of what it calls a Data-Memory Dependent Prefetcher, or DMP.
Apple’s relatively modern chips are affected by this bug. These are the M1, M1 Max and A14 SoCs. According to the researchers, the worst-case scenario of the DMP implementation in these chips could potentially leak data.
In their article, they revealed that the way Apple implemented the DMP is very different from how traditional DMPs are implemented. In the case of the Cupertino giant, their CPU cores never read the “prefetched” data….
