When processing command arguments for diagnostic operations, the utility tokenizes user-supplied input into an internal argument array without enforcing boundary checks on the maximum array capacity. An authenticated user with administrative access can exploit this vulnerability by supplying a crafted diagnostic command string containing an excessive number of tokenized arguments. This leads to a memory overwrite resulting in a denial of service (process crash).","categories":["Unclassified"],"product":"Fabric OS","vendor":"Brocade","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-87668","source_modified_at":"2026-10-08T13:46:29.700Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Fabric OS","vendor":"Brocade","versions":[{"status":"affected","version":"0","lessThan":"10.0.1","versionType":"Brocade FabricOS"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-87668","source_modified_at":"2026-10-08T13:46:29.700Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Fabric OS","ecosystem":null},"version":"10.0.1","basis":"first unaffected version stated in the CVE record"}],"cvss":6.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.0039,"percentile":0.31976,"score_date":"2026-10-23"},"published_at":"2026-10-08T03:00:54.306Z","modified_at":"2026-10-08T13:46:29.700Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-87668","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-08T13:46:29.700Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-87668","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://support.broadcom.com/external/content/SecurityAdvisories/0/39152"}],"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":"2026-10-08T13:44:07.006999Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-08T13:46:29.700Z","content_hash":"319e9a00620380386d69198d0675b876076da281cd93e6e6d310d8adc5858843"}}
