CVE-2026-23451

Estado: ModificadaAlta (7.5)—

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

bonding: prevent potential infinite loop in bond_header_parse()

bond_header_parse() can loop if a stack of two bonding devices is setup, because skb->dev always points to the hierarchy top.

Add new "const struct net_device *dev" parameter to (struct header_ops)->parse() method to make sure the recursion is bounded, and that the final leaf parse method is called.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Puntuación base: 7.5

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.44%
Percentil entre todas las CVEs puntuadas: 36
Fecha de la puntuación: 5/10/2026

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.

ExplotaciónT1190 Exploit Public-Facing Applicationinitial access45 %
Impacto principalT1499.004 Application or System Exploitationimpact70 %
Impacto secundarioT1068 Exploitation for Privilege Escalationprivilege escalation35 %

AV:N sin autenticación sugiere exposición remota (T1190), pero es bucle infinito por diseño (no clásico). Impacto principal DoS por agotamiento de recursos (CWE-835, infinite loop → T1499.004). Escalada potencial si kernel crash.

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.
