CVE-2026-74294

Estado: RecibidaAlta (7.3)—

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

ASoC: meson: aiu: Validate written enum values

The AIU HDMI and internal codec mux put callbacks use the written enum value with snd_soc_enum_item_to_val() before checking whether the value is valid for the enumeration.

Reject out-of-range values before converting the enum item, matching the validation already done by the G12A HDMI and internal codec mux controls.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:L, PR:L, UI:N indica escalada local sin interacción (T1068). La falta de validación de enum en controlesde audio kernel permite RCE o DoS; impacto de ejecución de código o denegación de servicio de audio.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
