CVE-2018-9420

Local information disclosure via uninitialized metadata padding

Published Nov 19, 2024 · Updated Nov 20, 2024

Information disclosure in Android 6.0 through 8.1 allows local users to read uninitialized camera metadata through Binder IPC. BnCameraService::onTransact returns camera metadata whose padding field is not initialized before the parcel crosses the Binder boundary. A local application needs no additional execution privileges or user interaction, and exposure is limited to process-memory remnants in the returned metadata padding.
