CVE-2007-3722

FreeBSD - Denial of Service via Scheduler CPU Billing Manipulation

Title source: llm
STIX 2.1

Description

The 4BSD process scheduler in the FreeBSD kernel 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."
