CVE-2025-53477

Estado: AnalizadaAlta (7.5)—

NULL Pointer Dereference vulnerability in Apache Nimble.

Missing validation of HCI connection complete or HCI command TX buffer could lead to NULL pointer dereference. This issue requires disabled asserts and broken or bogus Bluetooth controller and thus severity is considered low.

This issue affects Apache NimBLE: through 1.8.0.

Users are recommended to upgrade to version 1.9.0, which fixes the issue.

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.

Vulnerabilidad de desreferencia de NULL en Nimble (AV:N/AC:L/PR:N) que causa DoS por A:H en CVSS. Aunque requiere condiciones especiales (asserts deshabilitados, controlador Bluetooth bogus), se mapea a T1190 por red sin autenticación. T1499.004 por crash/indisponibilidad.

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.
