Later, we use scanf on this buffer but we don't\nensure that the string is terminated inside the buffer, this can lead to\nOOB read when using scanf. Fix this issue by using memdup_user_nul instead."

Actualmente, asignamos un b\u00fafer del kernel del tama\u00f1o de lbuf y copiamos lbuf del espacio de usuario a ese b\u00fafer. M\u00e1s adelante, usamos scanf en este b\u00fafer pero no nos aseguramos de que la cadena termine dentro del b\u00fafer, esto puede provocar una lectura OOB cuando usamos scanf. Solucione este problema utilizando memdup_user_nul en su lugar."
