{"id":"CVE-2026-104114","published":"2026-10-09T15:17:07.430","lastModified":"2026-10-09T17:16:44.647","description":"A NULL pointer dereference in the illumos Network Auto-Magic daemon (nwamd) allows a local user to crash the daemon. nwamd_door_switch() in usr/src/cmd/cmd-inet/lib/nwamd/door_if.c writes to the caller's request structure before checking that a request was supplied, and before checking the caller's credentials. Because the nwamd door at /etc/svc/volatile/nwam/nwam_door is accessible to all local users, an unprivileged user can issue a door_call() with no argument data to crash nwamd; repeated calls place the svc:/network/physical:nwam service into maintenance, stopping automatic network configuration. nwamd runs only when svc:/network/physical:nwam is enabled, which is not the default. The flaw has existed since 2010 (illumos-gate commit 6ba597c5), and affects any illumos distribution prior to illumos-gate commit 0f1064d9.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-476"],"vendors":[],"products":[],"references":[{"url":"https://github.com/illumos/illumos-gate/commit/0f1064d97f1a43778ddf87d4e438b99872aed1a0","tags":[]},{"url":"https://illumos.org/issues/18495","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/illumos/illumos-gate/commit/0f1064d97f1a43778ddf87d4e438b99872aed1a0","tags":[]}],"hasPoc":true,"ai":null}
