A big potential security flaw was just spotted in Apple chips and it all has to do with AI development — “LeftoverLocals” vulnerability could give hackers data from GPU local memory

A major security flaw that could put Apple GPUs at risk when using AI has been discovered. While some of the GPUs in question have already been patched to provide added security, many are still at risk.

AI processing can be a demanding prospect, so the raw power of GPUs is often pulled in to process that data. Essentially, when generative AI, like that found in text generation and prediction, is used, it runs a large language model (LLM) that analyses data incredibly quickly to get responses. Unfortunately, given this works in a way that many GPUs aren’t traditionally designed for, it has some unintended consequences.
