CVE-2025-9809

Estado: AnalizadaAlta (8.4)—

Out-of-bounds write in cdfs_open_cue_track in libretro libretro-common latest on all platforms allows remote attackers to execute arbitrary code via a crafted .cue file with a file path exceeding PATH_MAX_LENGTH that is copied using memcpy into a fixed-size buffer.

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 con AV:L/UI:A indica ejecución en el cliente mediante interacción del usuario (abrir archivo .cue malformado). El desbordamiento de búfer permite ejecución arbitraria de código.

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.
