Sensitive-data disclosure via unrestricted register access
Published Sep 4, 2023 · Updated Aug 2, 2024
Improper access control in MediaTek Chipset Bluetooth drivers on Android 13.0 allows local users to read sensitive register data. The driver fails to enforce access controls on its hardware register interface, exposing register reads and writes beyond the intended boundary. Exploitation requires local System execution privileges and no user interaction; the reported consequence is sensitive-information disclosure.
