When processing API request payloads (such as device configuration attributes or port mapping requests) the REST API service fails to properly validate incoming array counts and string lengths against internal buffer capacities. An authenticated attacker with REST API access can transmit crafted, oversized request parameters to induce memory corruption on the execution stack. This may result in a denial-of-service condition (daemon crash) or potential arbitrary code execution within the management process context.","categories":["Unclassified"],"product":"Fabric OS","vendor":"Brocade","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-87683","source_modified_at":"2026-10-08T12:57:01.812Z","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-2026-87683","source_modified_at":"2026-10-08T12:57:01.812Z","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":8.6,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00481,"percentile":0.40585,"score_date":"2026-10-23"},"published_at":"2026-10-08T01:07:17.780Z","modified_at":"2026-10-08T12:57:01.812Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-87683","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-08T12:57:01.812Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-87683","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/0/39077"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-08T12:56:45.842416Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-08T12:57:01.812Z","content_hash":"10b7e758927c99a4f3b90b0c816130766f0f4383676625c3eca6c91961049fb5"}}
