CVE-2011-1478  (opens in a new tab)
CWE-476  (opens in a new tab)

How to fix?

Upgrade RHEL:6 kernel-doc to version 0:2.6.32-71.24.1.el6 or higher.
This issue was patched in RHSA-2011:0421.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-doc package and not the kernel-doc package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

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.
