CVE-2026-86510

Estado: AplazadaAlta (8.6)—

A vulnerability has been found in D-Link DIR-822A A_101. Affected is the function tunnel_set_params of the component L2TP Control Message Parser. Such manipulation leads to out-of-bounds write. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.

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 indica acceso remoto con PR:L (requiere privilegios). Out-of-bounds write en parser de L2TP en router D-Link permite ejecución de código remota tras autenticación.

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.
