CVE-2026-74295

ASoC: codecs: hdac_hdmi: Validate written enum value

State: Published
Severity: 7.1 High
Published: Aug 15, 2026
Updated: Oct 16, 2026

Description

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

ASoC: codecs: hdac_hdmi: Validate written enum value

hdac_hdmi_set_pin_port_mux() uses the written enum value to index the texts array before calling snd_soc_dapm_put_enum_double(), which validates that the value is within the enum item range.

An out-of-range value can therefore make the driver read past the texts array before the helper rejects the write. Move the lookup after the helper has accepted the value.
