CVE-2023-40087

Estado: ModificadaAlta (8.8)—

En transcodeQ*ToFloat de btif_avrcp_audio_track.cc, existe una posible escritura fuera de los límites debido a una verificación de los límites faltante. Esto podría llevar a una escalada de privilegios del dispositivo emparejado sin necesidad de privilegios de ejecución adicionales. La interacción del usuario no es necesaria para la explotación.

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).
