CVE-2026-24183

Estado: AnalizadaAlta (7.8)—

NVIDIA Cumulus Linux contains a vulnerability in the user management component, where an unprivileged user could use improper privilege management on the system. A successful exploit of this vulnerability might lead to escalation of privileges.

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.

Vector CVSS AV:L/PR:L sin UI permite escalada local. CWE-250 (improper privilege management) y descripción explícita de 'escalation of privileges' confirman T1068 como explotación e impacto.

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.
