CVE-2025-29971

Estado: AnalizadaAlta (7.5)—

Out-of-bounds read in Web Threat Defense (WTD.sys) allows an unauthorized attacker to deny service over a network.

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.

Acceso de red sin autenticación (AV:N/PR:N/UI:N) con impacto de disponibilidad (A:H) en servicio de defensa web; DoS de red por lectura fuera de límites en driver del kernel.

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.
