CVE-2025-26436

Estado: AnalizadaAlta (7.8)—

In clearAllowBgActivityStarts of PendingIntentRecord.java, there is a possible way for an application to launch an activity from the background due to BAL Bypass. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

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.

CVE-2025-26436 permite escalada de privilegios local (AV:L, PR:L) sin interacción del usuario mediante un bypass BAL en Android. Impactos: obtención de permisos/acceso elevado (T1078) y ejecución de código de aplicación con privilegios escalados (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.
