Descriptions

include/linux/netdevice.h in the Linux kernel before 2.6.36 incorrectly uses macros for netdev_printk and its related logging implementation, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) by sending invalid packets to a VxLAN interface.

include/linux/netdevice.h en el kernel de Linux anterior a 2.6.36 utiliza incorrectamente los macros para netdev_printk y su implementación de registro relacionada, lo que permite a atacantes remotos causar una denegación de servicio (referencia a puntero nulo y caída del sistema) mediante el envió de paquetes inválidos a una interfaz VxLAN.

A NULL pointer dereference flaw was found in the way the Linux kernel's networking implementation handled logging while processing certain invalid packets coming in via a VxLAN interface. A remote attacker could use this flaw to crash the system by sending a specially crafted packet to such an interface.
