CVE-2026-64107 ASoC: codecs: pcm512x: fix null-ptr dereference in pcm512x_overclock_xxx_put()

What is CVE-2026-64107?

CVE-2026-64107 is a medium-severity vulnerability in Linux kernel, published on 19 Jul 2026. 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: codecs: pcm512x: fix null-ptr dereference in pcm512x_overclock_xxx_put()

In the pcm512x chipset driver, pcm512x_overclock_xxx_put() is defined as a general mixer kcontrol instead of a DAPM kcontrol, so struct snd_soc_dapm_context must not be accessed via snd_soc_dapm_kcontrol_to_dapm().

This causes a NULL pointer dereference, so it must be modified to use snd_soc_component_to_dapm().

Weakness: CWE-476
