Memory corruption via HIDL-controlled serializer buffer size
Published Jul 4, 2023 · Updated Aug 2, 2024
Memory corruption in Qualcomm Snapdragon Audio allows local privileged users to corrupt memory via a HIDL-controlled buffer size. The sva_model_serializer path trusts a memory size supplied by the HIDL client when copying model data, allowing the destination buffer to be overrun. High local privileges are required; successful corruption can expose or alter data and terminate the audio service.
