CVE-2007-3723

Status: ModifiedLow (2.1)—

The process scheduler in the Sun Solaris kernel does not make use of the process statistics kept by the kernel and performs scheduling based upon CPU billing gathered from periodic process sampling ticks, which allows local users to cause a denial of service (CPU consumption), as described in "Secretly Monopolizing the CPU Without Superuser Privileges."

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
