Kernel memory corruption via oversized sound model copy
Published May 6, 2024 · Updated Dec 16, 2025
Buffer overflow in Qualcomm Snapdragon audio firmware allows local users with high privileges to corrupt kernel memory during sound model registration. The registration path copies user-supplied sound-model data into a kernel buffer without verifying that the destination can hold the supplied size. Local high-privilege access is required; successful corruption can compromise confidentiality, integrity, and availability within the affected device.
