CVE-2011-1478 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.09% chance of exploitation in the next 30 days.
