CentOS Errata and Security Advisory CESA-2016:2047

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • Linux kernel built with the 802.1Q/802.1ad VLAN(CONFIG_VLAN_8021Q) OR Virtual eXtensible Local Area Network(CONFIG_VXLAN) with Transparent Ethernet Bridging(TEB) GRO support, is vulnerable to a stack overflow issue. It could occur while receiving large packets via GRO path as an unlimited recursion could unfold in both VLAN and TEB modules leading to a stack corruption in the kernel. (CVE-2016-7039, Important)
