CVE-2026-74295 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. 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.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
