  - 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:
