Memory corruption via audio channel-map access
Published Apr 7, 2025 · Updated Apr 7, 2025
Out-of-bounds write in Qualcomm Snapdragon audio firmware allows local users with low privileges to corrupt memory through audio controls. The MSM channel-map and mixer functions access memory outside a valid buffer boundary, but Qualcomm has not disclosed the specific faulty operation or input. Local low-privileged access is required, and no user interaction is needed; exploitation allows memory modification, limited disclosure, and a service interruption.
