CVE-2022-49250

Estado: AnalizadaAlta (7.1)—

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

ASoC: codecs: rx-macro: fix accessing compander for aux

AUX interpolator does not have compander, so check before accessing compander data for this.

Without this checkan array of out bounds access will be made in comp_enabled[] array.

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 sin interacción (AV:L, PR:L, UI:N) con escalada de confidencialidad e impacto en disponibilidad (C:H, A:H); desbordamiento de buffer en kernel podría permitir ejecución de código o denegación de servicio.

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.
