CVE-2018-9378

Local information disclosure via uninitialized Binder structures

Published Jan 28, 2025 · Updated Jan 28, 2025

Information disclosure in Android AudioPolicyService 6.0 through 8.1 allows local users to receive uninitialized data through Binder calls. BnAudioPolicyService::onTransact reads effect descriptors and audio_port_config values from Parcels into structures without zero-initializing them or checking read status, allowing uninitialized bytes to be returned. No additional execution privileges or user interaction are required; the consequence is limited to local disclosure, with no integrity or availability impact reported.
