Descriptions

The Background service in Allwinner R818 SoC Android Q SDK V1.0 is used to manage background applications. Malicious apps can use the interface provided by the service to set the number of applications allowed to run in the background to 0 and add themselves to the whitelist, so that once other applications enter the background, they will be forcibly stopped by the system, causing a denial of service.

El servicio Background del SDK de Android Q del SoC Allwinner R818 es usada para administrar las aplicaciones en segundo plano. Las aplicaciones maliciosas pueden usar la interfaz proporcionada por el servicio para establecer el número de aplicaciones permitidas para ejecutarse en segundo plano a 0 y añadirse a la lista blanca, de modo que una vez que otras aplicaciones entren en segundo plano, serán detenidas a la fuerza por el sistema, causando una denegación de servicio
