CVE-2026-96891

Estado: AplazadaCrítica (9.3)—

A vulnerability was identified in D-Link DIR-825 3.00b32. Affected is the function tunnel_set_params of the file tunnel.c of the component rp-l2tp. The manipulation of the argument peer_hostname  leads to out-of-bounds write. The attack may be initiated remotely.

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.
