Red Hat Security Advisory 2012-1430-01
Posted Nov 7, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-1430-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way socket buffers (skb) requiring TSO (TCP segment offloading) were handled by the sfc driver. If the skb did not fit within the minimum-size of the transmission queue, the network card could repeatedly reset itself. A remote attacker could use this flaw to cause a denial of service.
