Because the nwamd door at /etc/svc/volatile/nwam/nwam_door is accessible to all local users, an unprivileged user can issue a door_call() with no argument data to crash nwamd; repeated calls place the svc:/network/physical:nwam service into maintenance, stopping automatic network configuration. nwamd runs only when svc:/network/physical:nwam is enabled, which is not the default. The flaw has existed since 2010 (illumos-gate commit 6ba597c5), and affects any illumos distribution prior to illumos-gate commit 0f1064d9.","state":0,"publishedAt":"2026-10-09T14:22:14.611+00:00","modifiedAt":"2026-10-09T16:45:28.8+00:00","affected":[{"ecosystem":"https://illumos.org","name":"SUNWcs","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"illumos\",\n                    \"product\": \"illumos-gate\",\n                    \"platforms\": [\n                        \"x86\"\n                    ],\n                    \"collectionURL\": \"https://illumos.org\",\n                    \"packageName\": \"SUNWcs\",\n                    \"repo\": \"https://github.com/illumos/illumos-gate\",\n                    \"programFiles\": [\n                        \"usr/src/cmd/cmd-inet/lib/nwamd/door_if.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"6ba597c56d749c61b4f783157f63196d7b2445f0\",\n                            \"lessThan\": \"0f1064d97f1a43778ddf87d4e438b99872aed1a0\",\n                            \"changes\": [\n                                {\n                                    \"at\": \"0f1064d97f1a43778ddf87d4e438b99872aed1a0\",\n                                    \"status\": \"unaffected\"\n                                }\n                            ],\n                            \"versionType\": \"git\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"},{"ecosystem":"Vendor product","name":"OmniOS","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"OmniOS\",\n                    \"product\": \"OmniOS\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"any\",\n                            \"lessThan\": \"r151054\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"r151058\",\n                            \"lessThan\": \"r151058w\",\n                            \"changes\": [\n                                {\n                                    \"at\": \"r151058w\",\n                                    \"status\": \"unaffected\"\n                                }\n                            ],\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"r151056\",\n                            \"lessThan\": \"r151056aw\",\n                            \"changes\": [\n                                {\n                                    \"at\": \"r151056aw\",\n                                    \"status\": \"unaffected\"\n                                }\n                            ],\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"r151054\",\n                            \"lessThan\": \"r151054bw\",\n                            \"changes\": [\n                                {\n                                    \"at\": \"r151054bw\",\n                                    \"status\": \"unaffected\"\n                                }\n                            ],\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"affected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P","score":5.4,"severity":"MEDIUM"}],"references":["https://illumos.topicbox.com/groups/developer/T3b859664594b7762/cve-2026-104112-to-cve-2026-104117-denial-of-service-and-missing-authorization-in-door-servers","https://illumos.org/issues/18495","https://github.com/illumos/illumos-gate/commit/0f1064d97f1a43778ddf87d4e438b99872aed1a0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104114","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104114","identifiers":["CVE-2026-104114"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
