The vulnerability is that the Call management ("com.android.server.telecom") app patched by LG sends a lot of LG-owned implicit broadcasts that disclose sensitive data to all third-party apps installed on the same device. Those intents include data such as call states, durations, called numbers, contacts info, etc.
The Android application uses a Broadcast Receiver that receives an Intent but does not properly verify that the Intent came from an authorized source.
