Description
In p2p_copy_client_info of p2p.c, there is a possible out of bounds write due to a missing bounds check. This could lead to remote code execution if the target device is performing a Wi-Fi Direct search, with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-10 Android-11 Android-8.1 Android-9Android ID: A-172937525
