{"id":"CVE-2026-104113","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-104113","generatedAt":"2026-10-28T00:51:00.103Z","title":"A double free in the IP management daemon (ipmgmtd) of OmniOS and SmartOS allows a local user 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.","published":"2026-10-09T15:17:07.000Z","lastModified":"2026-10-09T17:16:44.000Z","status":"Awaiting Analysis","sourceIdentifier":"0ca53633-f0b5-4853-ba72-e0a2e62000d0","cvss":{"version":"4.0","score":5.4,"severity":"MEDIUM","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/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-415"],"affected":[],"epss":{"score":0.00116,"percentile":0.01603,"date":"2026-10-26","history":[{"date":"2026-10-10","score":0.00116,"percentile":0.01505}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.12%).
