CVE-2026-14297

Estado: Pendiente de análisisAlta (8.7)—
Detalles técnicos trazas, registros y código del informe original
A buffer overflow in the Bluetooth Continuous Glucose
     Monitoring Service (CGMS) Record Access Control Point (RACP) write handler
     allows an authenticated BLE peer to overflow a 20-byte static buffer into
     adjacent BSS memory. The exploitable impact cannot be predetermined - it
     is entirely dependent on the linker-assigned BSS layout of the specific
     firmware build, which may vary.

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 AV:A (red adyacente) con autenticación requerida (PR:N en contexto BLE) y desbordamiento de búfer en manejador RACP que permite corrupción de memoria BSS; impacto de ejecución de código por sobrescritura de memoria adyacente.

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.
