Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2007-3722 impacting freebsd freebsd. Evaluated with CVSS Base Score of 2.1 (UNKNOWN).

Original NVD Description

Source: NIST NVD
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."
