Local information disclosure via stale sensor timestamp
Published Jun 10, 2020 · Updated Aug 4, 2024
Use-after-free in the Android 9 and 10 media framework allows local users to read memory outside intended bounds without interaction. sendCaptureResult retains a sensor-timestamp reference into metadata, then calls code that can replace and reallocate that metadata before the reference is read. Exploitation requires local code execution but no user interaction; the documented consequence is information disclosure, not modification or interruption.
