"A Flaw in Millions of Apple, AMD, and Qualcomm GPUs Could Expose AI Data"

According to new research, a vulnerability called LeftoverLocals exists in multiple brands and models of mainstream GPUs, including Apple, Qualcomm, and AMD chips, and can allow an attacker to steal large amounts of data from a GPU's memory. To exploit the vulnerability, attackers must first establish some level of operating system access on a target's device. Modern computers and servers are designed to silo data, allowing multiple users to share the same processing resources while not being able to access each other's data. However, an attack through LeftoverLocals knocks down these barriers, enabling a hacker to pull data from vulnerable GPUs' local memory that they should not have access to and expose whatever data is available, which could include Large Language Model (LLM) queries and responses. This article continues to discuss the potential exploitation and impact of the LeftoverLocals vulnerability.
