Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: Intel: sof_sdw: Prevent jump to NULL add_sidecar callback In create_sdw_dailink() check that sof_end->codec_info->add_sidecar is not NULL before calling it. The original code assumed that if include_sidecar is true, the codec on that link has an add_sidecar callback. But there could be other codecs on the same link that do not have an add_sidecar callback.
