Descriptions
The IPv4 implementation in the Linux kernel before 4.5.2 mishandles destruction of device objects, which allows guest OS users to cause a denial of service (host OS networking outage) by arranging for a large number of IP addresses.
La implementación IPv4 en el kernel de Linux en versiones anteriores a 4.5.2 no maneja adecuadamente la destrucción de objetos de dispositivo, lo que permite a usuarios del SO invitado provocar una denegación de servicio (corte de la red del sistema operativo anfitrión) disponiendo un gran número de direcciones IP.
A security flaw was found in the Linux kernel's networking subsystem that destroying the network interface with huge number of ipv4 addresses assigned keeps "rtnl_lock" spinlock for a very long time (up to hour). This blocks many network-related operations, including creation of new incoming ssh connections.
The problem is especially important for containers, as the container owner has enough permissions to trigger this and block a network access on a whole host, outside the container.
