System compromise via unvalidated Audio DSP input
Published Jun 6, 2023 · Updated Aug 2, 2024
Memory corruption in Qualcomm Snapdragon Audio firmware allows local users to compromise data and service operation during recording. During audio recording, the Audio DSP supplies input that the firmware fails to validate, resulting in memory corruption. A local low-privileged user must reach the recording path; successful exploitation can compromise confidentiality, integrity, and availability.
