{"id":"CVE-2026-104113","published":"2026-10-09T15:17:07.270","lastModified":"2026-10-09T17:16:44.493","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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-415"],"vendors":[],"products":[],"references":[{"url":"https://github.com/TritonDataCenter/illumos-joyent/commit/TBD","tags":[]},{"url":"https://github.com/omniosorg/illumos-omnios/commit/670d853f335203ce8a66126cdbb25bfdba973036","tags":[]},{"url":"https://illumos.topicbox.com/groups/developer/T3b859664594b7762/cve-2026-104112-to-cve-2026-104117-denial-of-service-and-missing-authorization-in-door-servers","tags":[]}],"exploitRefs":[{"url":"https://github.com/TritonDataCenter/illumos-joyent/commit/TBD","tags":[]},{"url":"https://github.com/omniosorg/illumos-omnios/commit/670d853f335203ce8a66126cdbb25bfdba973036","tags":[]}],"hasPoc":true,"ai":null}
