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 chaninfo array. So fix this. Without this, its possible that we could corrupt struct wcd938xsdwpriv by accessing portmap array out of range with channel id instead of port id.
