CVE-2007-3721: Freebsd

Low severity, CVSS 2.1. EPSS: 0.3% chance of exploitation in the next 30 days.

The ULE process scheduler in the FreeBSD kernel gives preference to "interactive" processes that perform voluntary sleeps, which allows local users to cause a denial of service (CPU consumption), as described in "Secretly Monopolizing the CPU Without Superuser Privileges."
