{"id":"CVE-2026-104113","state":"PUBLISHED","title":"Double free in OmniOS and SmartOS ipmgmtd allows local users to crash the daemon","description":"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.","publishedAt":"2026-10-09T14:17:00.527Z","updatedAt":"2026-10-09T16:45:51.552Z","severity":{"score":5.4,"label":"Medium","version":"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","source":"illumos"},"assigner":"illumos","products":["OmniOS OmniOS"],"affected":[{"vendor":"OmniOS","product":"OmniOS","packageName":"SUNWcs","defaultStatus":"affected","versions":[{"version":"r151020","status":"affected","lessThan":"r151054","versionType":"custom"},{"version":"r151058","status":"affected","lessThan":"r151058w","changes":[{"at":"r151058w","status":"unaffected"}],"versionType":"custom"},{"version":"r151056","status":"affected","lessThan":"r151056aw","changes":[{"at":"r151056aw","status":"unaffected"}],"versionType":"custom"},{"version":"r151054","status":"affected","lessThan":"r151054bw","changes":[{"at":"r151054bw","status":"unaffected"}],"versionType":"custom"}],"platforms":["x86"],"programFiles":["usr/src/cmd/cmd-inet/lib/ipmgmtd/ipmgmt_door.c"]}],"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://github.com/omniosorg/illumos-omnios/commit/670d853f335203ce8a66126cdbb25bfdba973036","https://github.com/TritonDataCenter/illumos-joyent/commit/TBD"],"weaknesses":["CWE-415"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/104xxx/CVE-2026-104113.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-104113","state":"PUBLISHED","datePublished":"2026-10-09T14:17:00.527Z","dateUpdated":"2026-10-09T16:45:51.552Z","assignerShortName":"illumos","assignerOrgId":"0ca53633-f0b5-4853-ba72-e0a2e62000d0","dateReserved":"2026-10-01T18:07:53.956Z"},"containers":{"cna":{"title":"Double free in OmniOS and SmartOS ipmgmtd allows local users to crash the daemon","descriptions":[{"lang":"en","value":"A double free in the IP management daemon (ipmgmtd) of OmniOS and SmartOS allows a local user to crash the daemon.
