CVE-2024-46871

Estado: AnalizadaAlta (7.8)—

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Corrija el valor definido para AMDGPU_DMUB_NOTIFICATION_MAX [Por qué y cómo] En realidad, expone '6' tipos en la enumeración dmub_notification_type. No 5. El uso de un número menor para crear la matriz dmub_callback y dmub_thread_offload tiene el potencial de acceder a un elemento fuera del límite de la matriz. Arréglelo.

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.

Vulnerabilidad local (AV:L/PR:L) que permite escalada de privilegios (I:H) mediante out-of-bounds en array dmub_callback del kernel Linux. Potencial ejecución de código arbitrario o DoS.

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.
