Descriptions

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

ASoC: mediatek: Assign dummy when codec not specified for a DAI link

MediaTek sound card drivers are checking whether a DAI link is present
and used on a board to assign the correct parameters and this is done
by checking the codec DAI names at probe time.

If no real codec is present, assign the dummy codec to the DAI link
to avoid NULL pointer during string comparison.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ASoC: mediatek: Asignar dummy cuando el códec no está especificado para un enlace DAI Los controladores de la tarjeta de sonido MediaTek están comprobando si hay un enlace DAI presente y utilizado en una placa para asignar los parámetros correctos y esto se realiza comprobando los nombres DAI del códec en el momento de la sonda. Si no hay ningún códec real, asigne el códec ficticio al enlace DAI para evitar el puntero NULL durante la comparación de cadenas.
