Published Jan 4, 2022 · Updated Aug 3, 2024

Information disclosure in MediaTek kd_camera_hw on Android 10.0 and 11.0 allows local users to read uninitialized data. The driver allows uninitialized data to cross its trust boundary, but MediaTek has not published the affected function or data structure. Exploitation requires local access with Android System execution privileges and no user interaction, and the reported consequence is confidentiality loss only.
