Local information disclosure via unvalidated fence input
Published Dec 11, 2025 · Updated Dec 11, 2025
Information disclosure in Google Android's Android kernel allows local users to read sensitive data through AreFencesRegistered. AreFencesRegistered in gxp_fence_manager.cc processes input without validation sufficient to prevent an information leak; the specific unchecked field and read operation are not public. Low-privileged local access is required, while user interaction and additional execution privileges are not required; the reported consequence is confidentiality loss only.
