A local unprivileged attacker can abuse this flaw to crash systemd services or potentially execute code and elevate their privileges, by sending specially crafted dbus messages."

Un atacante no privilegiado local puede abusar de este fallo para bloquear los servicios de systemd o potencialmente ejecutar c\u00f3digo y elevar sus privilegios, mediante el env\u00edo de mensajes dbus especialmente dise\u00f1ados."
