CVE-2026-72410

Estado: RecibidaAlta (7.8)—

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

octeontx2-af: Validate NIX maximum LFs correctly

NIX maximum number of LFs can be set via devlink command but that can be done before assigning any LFs to a PF/VF. The condition used to check whether any LFs are assigned is incorrect. This patch fixes that condition.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 7.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.18%
Percentil entre todas las CVEs puntuadas: 6
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.

ExplotaciónT1068 Exploitation for Privilege Escalationprivilege escalation85 %

Vulnerabilidad local en kernel Linux (AV:L, PR:L) sin interacción permite escalada de privilegios a través de validación incorrecta de límites de funciones de red en octeontx2-af. Acceso local con privilegios limitados facilita ejecución de código y manipulación de datos del sistema.

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.
