{"id":"CVE-2026-104113","summary":"Double free in OmniOS and SmartOS ipmgmtd allows local users to crash the daemon","details":"A double free in the IP management daemon (ipmgmtd) of OmniOS and SmartOS allows a local user to crash the daemon. When authorizing a door request that modifies interface configuration, ipmgmt_handler() in usr/src/cmd/cmd-inet/lib/ipmgmtd/ipmgmt_door.c frees the caller's credential with ucred_free() immediately after reading the user ID, and frees it a second time on the error path if the authorization check fails. An unprivileged local user who does not hold the solaris.network.interface.config authorization can send such a request, for example IPMGMT_CMD_RESETIF, to the ipmgmtd door, causing ipmgmtd to abort; repeated requests place the svc:/network/ip-interface-management service into maintenance, preventing IP interface configuration. The early free was introduced in 2014 to support lx-branded zones (OmniOS commit 4c170900) and is not present in upstream illumos-gate. It affects OmniOS r151020 and later, and SmartOS, prior to the fix.","modified":"2026-10-11T07:00:57.703909406Z","published":"2026-10-09T14:17:00.527Z","database_specific":{"cna_assigner":"illumos","cwe_ids":["CWE-415"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/104xxx/CVE-2026-104113.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"r151058"},{"fixed":"r151058w"},{"introduced":"r151056"},{"fixed":"r151056aw"},{"introduced":"r151054"},{"fixed":"r151054bw"},{"introduced":"r151020"},{"fixed":"r151054"}]}]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/104xxx/CVE-2026-104113.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-104113"},{"type":"FIX","url":"https://github.com/TritonDataCenter/illumos-joyent/commit/TBD"},{"type":"FIX","url":"https://github.com/omniosorg/illumos-omnios/commit/670d853f335203ce8a66126cdbb25bfdba973036"},{"type":"ARTICLE","url":"https://illumos.topicbox.com/groups/developer/T3b859664594b7762/cve-2026-104112-to-cve-2026-104117-denial-of-service-and-missing-authorization-in-door-servers"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/omniosorg/illumos-omnios","events":[{"introduced":"0"},{"fixed":"670d853f335203ce8a66126cdbb25bfdba973036"}],"database_specific":{"source":"REFERENCES"}}],"versions":["onnv_144","onnv_143","onnv_142","onnv_141","onnv_140","onnv_139","onnv_138","onnv_137","onnv_136","onnv_135","onnv_134","onnv_133","onnv_132","onnv_131","onnv_130","onnv_129","onnv_128","onnv_127","onnv_126","onnv_125","onnv_124","onnv_123","onnv_122","onnv_121","onnv_120","onnv_119","onnv_118","onnv_117","onnv_116","onnv_115","onnv_114","onnv_113","onnv_112","onnv_111","onnv_110","onnv_109","onnv_108","onnv_107","onnv_","onnv_106","onnv_105","onnv_104","onnv_103","onnv_102","onnv_101","onnv_100","onnv_99","onnv_98","onnv_97","onnv_96","onnv_95","onnv_94","onnv_93","onnv_92","onnv_91","onnv_90","onnv_89","onnv_88","onnv_87","onnv_86","onnv_85","onnv_84","onnv_83","onnv_82","onnv_81","onnv_80","onnv_79","onnv_78","onnv_77","onnv_76","onnv_75","onnv_74","onnv_73","onnv_72","onnv_71","onnv_70","onnv_69","onnv_68","onnv_67","onnv_66","onnv_65","onnv_64","onnv_63","onnv_62","onnv_61","onnv_60","onnv_59","onnv_58","onnv_57","onnv_56","onnv_55","onnv_54","onnv_53","onnv_52","onnv_51","onnv_50","onnv_49","onnv_48","onnv_47","onnv_46","onnv_45","onnv_44","onnv_43","onnv_42","onnv_41","onnv_40","onnv_39","onnv_38","onnv_37","onnv_36","onnv_35","onnv_34","onnv_33","onnv_32","onnv_31","onnv_30","onnv_29","onnv_28","onnv_27","onnv_26","onnv_25","onnv_24","onnv_23","onnv_22","onnv_21","onnv_20","onnv_19","onnv_18"],"database_specific":{"vanir_signatures_modified":"2026-10-11T07:00:57Z","source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-104113.json","vanir_signatures":[{"id":"CVE-2026-104113-a97614f3","signature_type":"Line","signature_version":"v1","source":"https://github.com/omniosorg/illumos-omnios/commit/670d853f335203ce8a66126cdbb25bfdba973036","target":{"file":"usr/src/cmd/cmd-inet/lib/ipmgmtd/ipmgmt_door.c"},"deprecated":false,"digest":{"line_hashes":["298381756739132767320796100954115260494","133019350961963087075150217541824466935","324640063200016750816945259360219319187","2337954271442398907744236231188024279","128787396011463472516764321029087614799","273097059712255288959238292389125933310","4727405014489457474081475550178203966","191244543335672928605256189356186263098"],"threshold":0.9}},{"signature_type":"Function","signature_version":"v1","source":"https://github.com/omniosorg/illumos-omnios/commit/670d853f335203ce8a66126cdbb25bfdba973036","target":{"file":"usr/src/cmd/cmd-inet/lib/ipmgmtd/ipmgmt_door.c","function":"ipmgmt_handler"},"deprecated":false,"digest":{"length":1345,"function_hash":"338343569368610172075324576610663289242"},"id":"CVE-2026-104113-c48566aa"}]}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
