CVE-2025-4372

Estado: AnalizadaAlta (8.8)—

Use after free in WebAudio in Google Chrome prior to 136.0.7103.92 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Medium)

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.

Use-after-free requiere HTML malicioso que el usuario abre (UI:R); puede derivar en ejecución de código en el navegador mediante corrupción de heap, pero el nivel de certeza es moderado dado que el texto menciona 'potencialmente'.

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.
