CVE-2026-21087

Estado: AnalizadaAlta (8.6)—

Out-of-bounds write in libmdnie.so prior to SMR Sep-2026 Release 1 allows local attackers to execute arbitrary code with system server privilege.

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 AV:L sin UI indica acceso local sin interacción. CWE-787 (out-of-bounds write) en libmdnie.so permite ejecución arbitraria con privilegios de system server, típico de escalada local (T1068) que habilita ejecución de comandos (T1059).

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.
