CVE-2010-4251

HIGH

Linux Kernel < 2.6.34 - Denial of Service via Network Traffic Backlog

Title source: llm
STIX 2.1

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.
