CVE-2026-82334

Estado: AnalizadaCrítica (9.1)—

IBM Guardium Data Protection 12.0, 12.1, 12.2 es vulnerable a una lectura fuera de límites basada en montículo (heap) en el analizador del protocolo TDS7 LOGIN7. Un atacante remoto podría enviar un paquete TDS LOGIN7 especialmente manipulado que contenga valores de desplazamiento o longitud no válidos, lo que podría provocar la divulgación de información o una denegación de servicio.

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.

AV:N/PR:N indica acceso remoto sin privilegios (T1190). Heap overflow en parser permite lectura de memoria (CWE-125, C:H) e inanición de recursos (A:H).

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.
