FDN contact deletion via unauthorized broadcast
Published Jul 13, 2022 · Updated Aug 3, 2024
Unauthorized broadcast handling in Android on Android SoC devices allows attackers to delete fixed-dialing-number contacts through a third-party app. SprdContactsProvider processes an unauthorized broadcast as a request to delete an FDN contact; its underlying implementation is not public. Execution requires a third-party app on an affected Unisoc-based device, and the documented consequence is limited to FDN contact deletion.
