Resúmen: ¡Su sistema puede estar seriamente comprometido! /usr/sbin/wpa_supplicant intentó cargar un módulo del kernel. Descripción Detallada: SELinux le ha negado a wpa_supplicant acceso para cargar un módulo del kernel. Todos los programas confinados que necesiten cargar módulos del kernel deberían tener políticas definidas que les permitan hacerlo. Si una aplicación vulnerada intenta modificar el kernel, este AVC será generado. Este es un problema serio. Su equipo puede estar comprometido Permitiendo Acceso: Contact your security administrator and report this issue.
