CVE-2023-53145

Estado: AnalizadaAlta (7.8)—

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: btsdio: fix use after free bug in btsdio_remove due to race condition

In btsdio_probe, the data->work is bound with btsdio_work. It will be started in btsdio_send_frame.

If the btsdio_remove runs with a unfinished work, there may be a race condition that hdev is freed but used in btsdio_work. Fix it by canceling the work before do cleanup in btsdio_remove.

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 requiere acceso local con privilegios: T1068. Use-after-free en controlador Bluetooth permite ejecución de código arbitrario (CWE-416). Pista confirma T1059.

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.
