CVE-2023-52697 ASoC: Intel: sof_sdw_rt_sdca_jack_common: ctx->headset_codec_dev = NULL

What is CVE-2023-52697?

CVE-2023-52697 is a high-severity use after free vulnerability in Linux kernel, published on 17 May 2024. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

In the Linux kernel, the following vulnerability has been resolved:

ASoC: Intel: sof_sdw_rt_sdca_jack_common: ctx->headset_codec_dev = NULL

sof_sdw_rt_sdca_jack_exit() are used by different codecs, and some of them use the same dai name. For example, rt712 and rt713 both use "rt712-sdca-aif1" and sof_sdw_rt_sdca_jack_exit(). As a result, sof_sdw_rt_sdca_jack_exit() will be called twice by mc_dailink_exit_loop(). Set ctx->headset_codec_dev = NULL; after put_device(ctx->headset_codec_dev); to avoid ctx->headset_codec_dev being put twice.
