## What is CVE-2026-104113?

CVE-2026-104113 is a medium-severity use after free vulnerability in OmniOS, published on 9 Oct 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official 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.

Weakness: CWE-415 (Double Free)

Check this codebase for CVE-2026-104113 and fix it if it is affected.

What it is: CVE-2026-104113 is a medium-severity use after free vulnerability in OmniOS, published on 9 Oct 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-104113 in the wild and no public exploit code.

Affected product: OmniOS. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
