CVE-2025-38329

Estado: AnalizadaAlta (7.1)—

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

firmware: cs_dsp: Fix OOB memory read access in KUnit test (wmfw info)

Detalles técnicos trazas, registros y código del informe original
KASAN reported out of bounds access - cs_dsp_mock_wmfw_add_info(),
because the source string length was rounded up to the allocation size.

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.

Acceso local (AV:L) sin interacción del usuario (UI:N) con privilegios normales (PR:L) permite escalada vía lectura fuera de límites (CWE-125) en kernel Linux, potencial para ejecución de código elevado.

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.
