En todas las distribuciones de Android de CAF (Android for MSM, Firefox OS for MSM y QRD Android) que utilizan el kernel de Linux, podría ocurrir un posible desbordamiento de búfer al incrementar el log_buf de tipo uint64_t en la función memcpy, ya que el puntero log_buf puede acceder a la memoria más allá del tamaño para almacenar los datos tras el incremento de punteros.
