CVE-2015-1525Public exploit

Audio service outage via null address dereference

Published Jan 24, 2020 · Updated Aug 6, 2024

Denial of service in Android before 5.1 allows attackers to interrupt the audio_policy service through a crafted local application. AudioPolicyManagerBase::getDeviceConnectionState constructs a String8 from an unchecked device_address pointer, so a supplied NULL address triggers a null-pointer dereference. The crafted application must be installed and run on the device; the documented consequence is an audio_policy outage rather than data access or code execution.
