Researchers discovered a new vulnerability that could leak data to an attacker. Fortunately, it's pretty benign for now.
Researchers have released details of an Apple Silicon vulnerability dubbed “Augury.” However, it doesn’t seem to be a huge issue at the moment.
This could possibly leak data that’s not read because it gets dereferenced by the prefetcher. Apple’s implementation is different from a traditional prefetcher as explained by the paper. David Kohlbrenner, assistant professor at the University of Washington, downplayed the impact of Augery, noting that Apple’s DMP “is about the weakest DMP an attacker can get.”
