Demand for graphics processing units or GPUs has exploded in recent years as video rendering and artificial intelligence systems have expanded the need for processing power. And while most of the most visible shortages (and soaring stock prices) relate to top-tier PC and server chips, mobile graphics processors are the version that everyone with a smartphone is using everyday. So vulnerabilities in these chips or how they’re implemented can have real-world consequences. That’s exactly why Google’s Android vulnerability hunting red team set its sights on open-source software from the chip giant Qualcomm that’s widely used to implement mobile GPUs.
At the Defcon security conference in Las Vegas on Friday, three Google researchers presented more than nine vulnerabilities—now patched—that they discovered in Qualcomm’s Adreno GPU, a suite of software used to coordinate between GPUs and…
