CVE-2008-5713

Published: 24 December 2008

The __qdisc_run function in net/sched/sch_generic.c in the Linux kernel before 2.6.25 on SMP machines allows local users to cause a denial of service (soft lockup) by sending a large amount of network traffic, as demonstrated by multiple simultaneous invocations of the Netperf benchmark application in UDP_STREAM mode.

From the Ubuntu Security Team

It was discovered that in certain situations the network scheduler did not correctly handle very large levels of traffic. A local attacker could produce a high volume of UDP traffic resulting in a system hang, leading to a denial of service.
