{"schema":"threatline.record/2","record":{"id":"CVE-2026-104115","aliases":[],"summary":"Stack buffer overflow in illumos reparsed nfs-basic plugin allows local users to crash the daemon","details":"A stack-based buffer overflow in the illumos reparse point daemon (reparsed) allows a local user to crash the daemon. get_fs_locations() in usr/src/cmd/fs.d/nfs/rp_basic/libnfs_basic.c, part of the nfs-basic reparse plugin, copies the host and path components of a reparse string into a fixed 1024-byte stack buffer without checking their length. 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.","categories":["Unclassified"],"product":"illumos-gate","vendor":"illumos","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104115","source_modified_at":"2026-10-15T18:13:25.024Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"illumos-gate","vendor":"illumos","versions":[{"status":"affected","version":"2f172c55ef76964744bc62b4500ece87f3089b4d","lessThan":"6a2df4aa5381599179ab6afb3165db81960dee35","changes":[{"at":"6a2df4aa5381599179ab6afb3165db81960dee35","status":"unaffected"}],"versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104115","source_modified_at":"2026-10-15T18:13:25.024Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"OmniOS","vendor":"OmniOS","versions":[{"status":"affected","version":"any","lessThan":"r151054","versionType":"custom"},{"status":"affected","version":"r151058","lessThan":"r151058w","changes":[{"at":"r151058w","status":"unaffected"}],"versionType":"custom"},{"status":"affected","version":"r151056","lessThan":"r151056aw","changes":[{"at":"r151056aw","status":"unaffected"}],"versionType":"custom"},{"status":"affected","version":"r151054","lessThan":"r151054bw","changes":[{"at":"r151054bw","status":"unaffected"}],"versionType":"custom"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104115","source_modified_at":"2026-10-15T18:13:25.024Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"illumos-gate","ecosystem":null},"version":"6a2df4aa5381599179ab6afb3165db81960dee35","basis":"first unaffected version stated in the CVE record"}],"cvss":5.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00137,"percentile":0.02861,"score_date":"2026-10-23"},"published_at":"2026-10-09T14:24:52.028Z","modified_at":"2026-10-15T18:13:25.024Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-104115","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T18:13:25.024Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-104115","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","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":["mailing-list"]},{"source":"CVE List","url":"https://illumos.org/issues/18496","tags":["issue-tracking"]},{"source":"CVE List","url":"https://github.com/illumos/illumos-gate/commit/6a2df4aa5381599179ab6afb3165db81960dee35","tags":["patch"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-15T18:12:53.428116Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T18:13:25.024Z","content_hash":"4a5a3cfa1509c743bf66fbc1ff817ddea2880179b1c776c7d0379abe149692b9"}}
