CVE-2006-6653
CWE-20Published: December 20, 2006· Updated: Jun 16, 2026
1.7
CVSS v3.1
Official Description
The accept function in NetBSD-current before 20061023, NetBSD 3.0 and 3.0.1 before 20061024, and NetBSD 2.x before 20061029 allows local users to cause a denial of service (socket consumption) via an invalid (1) name or (2) namelen parameter, which may result in the socket never being closed (aka "a dangling socket").
Technical Analysis
CVE-2006-6653 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
