Descriptions

In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: wcd938x: fix incorrect used of portid Mixer controls have the channel id in mixer->reg, which is not same
as port id. port id should be derived from chan_info array.
So fix this. Without this, its possible that we could corrupt
struct wcd938x_sdw_priv by accessing port_map array out of range
with channel id instead of port id.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ASoC: códecs: wcd938x: corrige el uso incorrecto del puerto Los controles del mezclador tienen la identificación del canal en mezclador->reg, que no es la misma que la identificación del puerto. La identificación del puerto debe derivarse de la matriz chan_info. Entonces arregla esto. Sin esto, es posible que podamos dañar la estructura wcd938x_sdw_priv accediendo a la matriz port_map fuera del rango con la identificación del canal en lugar de la identificación del puerto.
