CVE-2022-49251

Estado: AnalizadaAlta (7.1)—

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

ASoC: codecs: va-macro: 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.

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 (acceso local) sin interacción indica T1068. La vulnerabilidad de out-of-bounds en enums permite corrupción de memoria que podría llevar a ejecución de código arbitrario con privilegios elevados en el kernel de Linux.

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.
