CVE-2010-4251
HIGHLinux Kernel < 2.6.34 - Denial of Service via Network Traffic Backlog
Title source: llmDescription
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.
