CVE-2010-4251 Information

Description

The socket implementation in net/core/sock.c in the Linux kernel before 2.6.34 does not properly manage a backlog of received packets which allows remote attackers to cause a denial of service (memory consumption) by sending a large amount of network traffic as demonstrated by netperf UDP tests.
