Description

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