CVE-2026-14316

Estado: Pendiente de análisisAlta (8.1)—

The revoked-key error path builds a human-readable failure reason using sprintf() into a heap buffer. The allocated buffer is too small for the final formatted message. When sprintf() writes the full message, it can write past the end of the heap allocation.

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 AV:N/UI:R indica explotación remota con interacción del usuario (T1203). Buffer overflow en sprintf() permite ejecución de código arbitrario (T1059) e infiltración de memoria (T1565.001).

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.
