Exploit públicoDisponiblePrueba de concepto en GitHub (no verificada)

Existen vulnerabilidades de use-after-free en las funciones l2cap_connect y l2cap_le_connect_req del kernel de Linux net/bluetooth/l2cap_core.c que pueden permitir la ejecución de código y la pérdida de memoria del kernel (respectivamente) de forma remota a través de Bluetooth. Un atacante remoto podría ejecutar código que filtre la memoria del kernel a través de Bluetooth si se encuentra cerca de la víctima. Recomendamos actualizar al commit anterior https://github.com/torvalds/linux/commit/711f8c3fb3db61897080468586b970c87c61d9e4

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).

Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
