CVE-2025-38423

Estado: AnalizadaAlta (7.8)—

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

ASoC: codecs: wcd9375: Fix double free of regulator supplies

Driver gets regulator supplies in probe path with devm_regulator_bulk_get(), so should not call regulator_bulk_free() in error and remove paths to avoid double free.

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.

Vulnerabilidad de double free (CWE-415) en controlador de kernel con acceso local (AV:L, PR:L) sin interacción requerida, permitiendo ejecución de código arbitrario con escalada de privilegios.

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.
