CRITICAL

Linux Kernel 5.14-5.14, <5.15.22, 5.16-5.16.8, >=5.17 - Uncontrolled Resource Consumption in ASoC WCD938x Mixer Control

Title source: llm

Description

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.
