A malicious application may cause unexpected changes in memory shared between processes. A memory corruption issue was addressed with improved state management. This issue is fixed in macOS Monterey 12.4.

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.

Acceso local (AV:L) sin interacción del usuario (UI:N) indica escalada de privilegios (T1068). La corrupción de memoria compartida entre procesos permite tanto elevación de privilegios como lectura de datos sensibles en memoria.

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.
