UnknownEPSS 0.26%

Last modified

CVE-2007-3722 is a vulnerability of currently unknown severity. 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.". EPSS estimates a 0.26% chance of exploitation in the next 30 days.
