CVE-2011-2723 at MITRE

Description

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.

NVD CVSS v2 Base Score: 5.7 (AV:A/AC:M/Au:N/C:N/I:N/A:C)

Novell/SUSE information

Note from the SUSE Security Team

This issue only affects kernels that have the generic checksum offload infrastructure, including kernels after 2.6.29. Earlier kernels ando SUSE Linux Enterprise releases up to and including SUSE Linux Enterprise 10 are not affected.
