CVE-2022-49251
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
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
- Puntuación base: 7.1
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.27%
- Percentil entre todas las CVEs puntuadas: 17
- Fecha de la puntuación: 6/10/2026
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.
- Explotación
T1068Exploitation for Privilege Escalationprivilege escalation92 % - Impacto principal
T1059Command and Scripting Interpreterexecution75 %
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.
