What to do
AI-suggested
A fix has been implemented in the Linux kernel to add proper memory release in the wcd937x_soc_codec_probe() function. Users should update to the fixed kernel version once available. No additional mitigation is required beyond applying the official patch.
Description
A potential memory leak vulnerability was identified and fixed in the Linux kernel's ASoC codec driver for wcd937x. The issue occurs in the wcd937x_soc_codec_probe() function when snd_soc_dapm_new_controls() or snd_soc_dapm_add_routes() fails, causing allocated memory for 'wcd937x->clsh_info' to not be released properly. This flaw could lead to resource exhaustion affecting system availability.
