Security researchers at Trail of Bits have discovered a vulnerability in a number of graphic processor units (GPUs) made by Apple, Qualcomm, AMD, and Imagination. They’ve named the flaw LeftoverLocals. They’ve demonstrated an exploit where an attacker who has local access to the device can read data in the GPU which was left over from earlier processing, hence the name. The proof of concept allowed them to accurately read the results of an AI chatbot query.
