Local memory disclosure via undersized escape input
Published Sep 24, 2025 · Updated Sep 24, 2025
Buffer over-read in Qualcomm Snapdragon video-engine firmware allows local users to disclose memory through undersized escape input data. The video engine accepts escape input shorter than its required minimum and reads beyond the supplied buffer, exposing adjacent data. Exploitation requires low-privilege local access and no user interaction; Qualcomm has not disclosed the specific escape handler or exposed data.
