CVE-2025-21006

Estado: AnalizadaAlta (7.8)—

Out-of-bounds write in handling of macro blocks for MPEG4 codec in libsavsvc.so prior to Android 15 allows local attackers to write out-of-bounds memory.

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/PR:L sin UI permite escalada de privilegios local. CWE-787 (buffer overflow) en libsavsvc.so puede derivar en ejecución de código arbitrario (T1059) con permisos elevados.

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.
