Local memory corruption via sound model registration
Published May 6, 2025 · Updated Feb 26, 2026
Out-of-bounds write in Qualcomm Snapdragon audio kernel drivers allows local users to corrupt memory during sound model registration. During voice-activation setup, the audio kernel driver writes beyond an intended buffer while registering a sound model; Qualcomm has not identified the faulty function or field. Low-privileged local access is required, and successful exploitation exposes memory while allowing limited modification or service interruption.
