NetBSD 2.0 before 2.0.4, 2.1 before 2.1.1, and 3, when the kernel is compiled with "options DIAGNOSTIC," allows local users to cause a denial of service (kernel assertion panic) via a negative linger time in the SO_LINGER socket option.

Security readout for executives and security teams

This is a local denial-of-service issue in certain NetBSD kernels built with the DIAGNOSTIC option. A local user could trigger a kernel assertion panic through an invalid SO_LINGER socket setting, causing an outage. It is mainly relevant to legacy NetBSD systems with local user access. Exposure is likely limited to legacy NetBSD hosts, especially multi-user systems or appliances using DIAGNOSTIC kernels. Systems without local untrusted users or without the DIAGNOSTIC kernel option have lower practical exposure based on the CVE description. Treat this as a legacy availability risk. It is not internet-scale remote compromise, but affected multi-user NetBSD systems could be crashed by local users. Prioritize remediation where the host supports critical services or grants local access to untrusted users. Mitigation focus: Upgrade NetBSD 2.0 systems to 2.0.4 or later vendor-fixed guidance.; Upgrade NetBSD 2.1 systems to 2.1.1 or later vendor-fixed guidance.; Review NetBSD-SA2005-012 for NetBSD 3 branch remediation details..
