CVE-2022-49249

Estado: AnalizadaAlta (7.1)—

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

ASoC: codecs: wc938x: fix accessing array out of bounds for enum type

Accessing enums using integer would result in array out of bounds access on platforms like aarch64 where sizeof(long) is 8 compared to enum size which is 4 bytes.

Fix this by using enumerated items instead of integers.

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 sin UI indica escalada local. Array out of bounds en driver de audio (wc938x) permite ejecución de código o DoS; CWE-125 es lectura fuera de límites que puede llevar a ejecución arbitraria.

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.
