CVE-2025-47350

Memory corruption via concurrent DSP mapping requests

Published Dec 18, 2025 · Updated Dec 18, 2025

Use-after-free in Qualcomm Snapdragon DSP services allows local users to corrupt memory through concurrent mapping and unmapping requests. The service mishandles overlapping requests from a user-space application, allowing a memory object to be accessed after its lifetime ends. Low-privilege local access is required; successful exploitation compromises data confidentiality and integrity and can interrupt the affected component.
