A security flaw named LeftoverLocals lets attackers access data that has been processed in a device’s GPU, and while Apple says A17 iPhone and M3 Macs have fixes, older models do not.

The report, and the naming of LeftoverLocals, comes from Trail of Bits, which previously demonstrated how Apple’s walled garden iPhone security can benefit hackers. The organization now says it has found “vulnerability that allows recovery of data from GPU local memory created by another process on Apple, Qualcomm, AMD, and Imagination GPUs.”
It’s a particularly significant vulnerability both because of the volume of data that may be read, and also because GPUs are being increasingly used in AI for processing of Large Language Models (LLMs.)
