CWE-20  (opens in a new tab)

How to fix?

Upgrade RHEL:6 kernel-firmware to version 0:2.6.32-131.17.1.el6 or higher.
This issue was patched in RHSA-2011:1350.

NVD Description

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

The skb_gro_header_slow function in include/linux/netdevice.h in the Linux kernel before 2.6.39.4, when Generic Receive Offload (GRO) is enabled, resets certain fields in incorrect situations, which allows remote attackers to cause a denial of service (system crash) via crafted network traffic.
