Vulnerability from github – Published: 2025-05-20 18:30 – Updated: 2025-11-17 15:30

Details

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

ASoC: codecs: wcd937x: fix a potential memory leak in wcd937x_soc_codec_probe()

When snd_soc_dapm_new_controls() or snd_soc_dapm_add_routes() fails, wcd937x_soc_codec_probe() returns without releasing 'wcd937x->clsh_info', which is allocated by wcd_clsh_ctrl_alloc. Add wcd_clsh_ctrl_free() to prevent potential memory leak.

Severity

5.5 (Medium)
