Descriptions

In the Linux kernel, the following vulnerability has been resolved:

ASoC: mediatek: sof-common: Add NULL check for normal_link string

It's not granted that all entries of struct sof_conn_stream declare
a `normal_link` (a non-SOF, direct link) string, and this is the case
for SoCs that support only SOF paths (hence do not support both direct
and SOF usecases).

For example, in the case of MT8188 there is no normal_link string in
any of the sof_conn_stream entries and there will be more drivers
doing that in the future.

To avoid possible NULL pointer KPs, add a NULL check for `normal_link`.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ASoC: mediatek: sof-common: Agregar verificación NULL para la cadena normal_link No se garantiza que todas las entradas de la estructura sof_conn_stream declaren una cadena `normal_link` (un enlace directo no SOF) , y este es el caso de los SoC que solo admiten rutas SOF (por lo tanto, no admiten casos de uso directos y SOF). Por ejemplo, en el caso de MT8188 no hay una cadena normal_link en ninguna de las entradas de sof_conn_stream y habrá más controladores que lo hagan en el futuro. Para evitar posibles KP de puntero NULL, agregue una verificación NULL para `normal_link`.
