CVE-2025-2509

Estado: AnalizadaAlta (7.8)—

Out-of-Bounds Read in Virglrenderer in ChromeOS 16093.57.0 allows a malicious guest VM to achieve arbitrary address access within the crosvm sandboxed process, potentially leading to VM escape via crafted vertex elements data triggering an out-of-bounds read in util_format_description.

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.

AV:L/PR:L sin UI indica escalada local. El acceso OOB en Virglrenderer desde guest VM malicioso permite escape de sandbox con código arbitrario, escalando privilegios en crosvm.

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.
