Published Oct 17, 2022 · Updated May 13, 2025

Use-after-free memory corruption in Qualcomm Snapdragon Mobile multimedia allows local users to alter data and interrupt the device. After callback registration fails, the multimedia component continues using memory it has freed; Qualcomm has not disclosed the affected function or object. Exploitation requires code running locally but no prior privileges or user interaction, and the corruption also exposes confidential data.
