CVE-2025-39972

Estado: AplazadaAlta (8.8)—

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

i40e: fix idx validation in i40e_validate_queue_map

Ensure idx is within range of active/initialized TCs when iterating over vf->ch[idx] in i40e_validate_queue_map().

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Puntuación base: 8.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.15%
Percentil entre todas las CVEs puntuadas: 4
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 escalation95 %
Impacto principalT1059 Command and Scripting Interpreterexecution75 %
Impacto secundarioT1499.004 Application or System Exploitationimpact70 %

Acceso local sin interacción (AV:L/PR:L/UI:N) en kernel Linux. Validación deficiente de índices en i40e_validate_queue_map permite escalada de privilegios. Impactos: ejecución de código kernel y potencial DoS por corrupción de memoria.

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.
