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.
