Descriptions
The napi_reuse_skb function in net/core/dev.c in the Generic Receive Offload (GRO) implementation in the Linux kernel before 2.6.38 does not reset the values of certain structure members, which might allow remote attackers to cause a denial of service (NULL pointer dereference) via a malformed VLAN frame.
La función napi_reuse_skb de net/core/dev.c en la implementación Generic Receive Offload (GRO) en el kernel de Linux anteriores a v2.6.38 no restablece los valores de algunos miembros de la estructura, lo que podría permitir a atacantes remotos provocar una denegación de servicio (puntero a NULL) a través de una manupulación de una trama VLAN.
