CVE-2024-49871

In the Linux kernel, the following vulnerability has been resolved: Input: adp5589-keys - fix NULL pointer dereference We register a devm action to call adp5589_clear_config() and then pass the i2c client as argument so that we can call i2c_get_clientdata() in order to get our device object. However, i2c_set_clientdata() is only being set at the end of the probe function which means that we'll get a NULL pointer dereference in case the probe function fails early.

Summary		(es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: Entrada: adp5589-keys - corrección de la desreferencia de puntero NULL Registramos una acción devm para llamar a adp5589_clear_config() y luego pasamos el cliente i2c como argumento para que podamos llamar a i2c_get_clientdata() para obtener nuestro objeto de dispositivo. Sin embargo, i2c_set_clientdata() solo se establece al final de la función de sondeo, lo que significa que obtendremos una desreferencia de puntero NULL en caso de que la función de sondeo falle antes.
