CVE-2006-6656: Unspecified vulnerability in ptrace in NetBSD-current before 20061027, NetBSD 3.0 and 3.0.1 before 20061027...

Unspecified vulnerability in ptrace in NetBSD-current before 20061027, NetBSD 3.0 and 3.0.1 before 20061027, and NetBSD 2.x before 20061119 allows local users to read kernel memory and obtain sensitive information via certain manipulations of a PT_LWPINFO request, which leads to a memory leak and information leak.

Security readout for executives and security teams

CVE-2006-6656 is an old NetBSD ptrace flaw that could let a local user read kernel memory and obtain sensitive information. It requires local access, so the main business concern is shared or multi-user NetBSD systems, especially legacy hosts still running affected 2.x, 3.0, 3.0.1, or NetBSD-current snapshots from the affected dates. Exposure is likely limited to legacy NetBSD systems matching the affected branches and dates. Internet-facing status is less relevant because the described attacker position is local user access. Modern systems are unlikely affected unless they run unpatched historical NetBSD builds. Treat as a targeted legacy-system cleanup item, not an emergency internet-wide threat. Prioritize if affected NetBSD hosts allow multiple users, host sensitive workloads, or remain unpatched in production. Mitigation focus: Identify NetBSD hosts and versions, including legacy or embedded deployments.; Upgrade affected NetBSD branches to vendor-corrected builds after the stated fixed dates.; Review NetBSD-SA2006-025 for branch-specific remediation guidance..
