CVE-2024-47721

Estado: ModificadaAlta (7.1)—

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

wifi: rtw89: remove unused C2H event ID RTW89_MAC_C2H_FUNC_READ_WOW_CAM to prevent out-of-bounds reading

The handler of firmware C2H event RTW89_MAC_C2H_FUNC_READ_WOW_CAM isn't implemented, but driver expects number of handlers is NUM_OF_RTW89_MAC_C2H_FUNC_WOW causing out-of-bounds access. Fix it by removing ID.

Addresses-Coverity-ID: 1598775 ("Out-of-bounds read")

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 (UI:N) en kernel de Linux permite lectura fuera de límites (CWE-125) de memoria sensible del controlador Wi-Fi, escalando privilegios locales.

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.
