CVE-2007-3720 Information

Description

The process scheduler in the Linux kernel 2.4 performs scheduling based on CPU billing gathered from periodic process sampling ticks which allows local users to cause a denial of service (CPU consumption) by performing voluntary nanosecond sleeps that result in the process not being active during a clock interrupt as described in \Secretly Monopolizing the CPU Without Superuser Privileges.\
