Quote:Researchers at the University of California, Riverside have identified three practical side-channel attacks that work on Nvidia GPUs. These attacks can be used to compromise someone's passwords, snoop on their online activities, and use machine learning to discover a secret neural network's structure. The paper focused on Nvidia graphics cards, but the researchers also informed AMD and Intel of the vulnerabilities and will continue to investigate them.

You can read the full paper detailing these attacks via UC Riverside's website. The school said it contacted Nvidia about the attacks and was told the company planned to "publish a patch that offers system administrators the option to disable access to performance counters from user-level processes." After informing AMD and Intel about the attacks, the researchers moved to investigate the possibility of these attacks working on Android smartphones.
