Local information disclosure via AVCS buffer over-read
Published Feb 6, 2024 · Updated Aug 6, 2024
Buffer over-read in Qualcomm Snapdragon Audio firmware allows local users to disclose data through an ADSP payload sent to AVCS services. Qualcomm identifies the locus only as Audio access to AVCS services from an ADSP payload and does not disclose the specific function or missing bounds check. A low-privilege local context is required; successful exploitation exposes protected data and can also interrupt the affected service.
