The reparsed door at /var/run/reparsed_door is readable by all users and the door server does not check the caller's credentials, so an unprivileged local user can send an nfs-basic request with an overlong host or path component to overflow the buffer. On systems built with stack protection, which is the default, this causes reparsed to abort; repeated requests place the svc:/system/filesystem/reparse service into maintenance. The service is disabled by default. The flaw has existed since 2009 (illumos-gate commit 2f172c55), and affects any illumos distribution prior to illumos-gate commit 6a2df4aa.","published":"2026-10-09T15:17:08.000Z","lastModified":"2026-10-15T19:17:14.000Z","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-121"],"affected":[],"epss":{"score":0.00137,"percentile":0.03109,"date":"2026-10-26","history":[{"date":"2026-10-10","score":0.00137,"percentile":0.02729}]},"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 (0.14%).
