CVE-2024-50125

Estado: ModificadaAlta (7.8)—

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

Bluetooth: SCO: Fix UAF on sco_sock_timeout

conn->sk maybe have been unlinked/freed while waiting for sco_conn_lock so this checks if the conn->sk is still valid by checking if it part of sco_sk_list.

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/UI:N indica escalada local; UAF (CWE-416) en kernel Bluetooth permite ejecución de código arbitrario con contexto elevado.

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.
