Se ha detectado un fallo en el controlador de dispositivo udmabuf del kernel de Linux, dentro de un manejador de fallos. Este problema se produce debido a la falta de una validación adecuada de los datos proporcionados por el usuario, lo que puede provocar un acceso a memoria más allá del final de un array. Esto podría permitir a un atacante escalar privilegios y ejecutar código arbitrario en el contexto del kernel.

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.
