The procfs implementation 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 (kernel panic) by attempting to access /emul/linux/proc/0/stat on a procfs filesystem that was mounted with mount_procfs -o linux, which results in a NULL pointer dereference.

Security readout for executives and security teams

CVE-2006-6655 is an old NetBSD local denial-of-service issue. A local user could trigger a kernel panic by accessing a specific Linux-compatible procfs path when procfs was mounted with the linux option. Business impact is mainly unexpected system crashes on affected legacy NetBSD systems. Exposure is likely limited to legacy NetBSD systems running affected versions with Linux procfs emulation mounted. Internet-facing exposure is not indicated by the sources because exploitation requires local user access. Prioritize if the organization still operates legacy NetBSD hosts with local user access. For most modern environments, urgency is low, but unpatched affected systems can suffer reliable outages. Mitigation focus: Upgrade affected NetBSD systems to versions after the fixed dates identified by the advisory.; Review NetBSD-SA2006-026 and current vendor guidance for supported remediation paths.; Disable or avoid linux-option procfs mounts where not operationally required..
