Descriptions
lxc-user-nic in Linux Containers (LXC) allows local users with a lxc-usernet allocation to create network interfaces on the host and choose the name of those interfaces by leveraging lack of netns ownership check.
lxc-user-nic en Linux Containers (LXC) permite a usuarios locales con una asignación lxc-usernet crear interfaces de red en el host y elegir el nombre de esas interfaces aprovechando la falta de verificación de propiedad de netns.
Jann Horn discovered that LXC incorrectly verified permissions when creating virtual network interfaces. A local attacker could possibly use this issue to create virtual network interfaces in network namespaces that they do not own.
