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.","state":0,"publishedAt":"2026-10-08T01:07:17.78+00:00","modifiedAt":"2026-10-08T12:57:01.812+00:00","affected":[{"ecosystem":"Vendor product","name":"Fabric OS","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Brocade\",\n                    \"product\": \"Fabric OS\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"10.0.1\",\n                            \"versionType\": \"Brocade FabricOS\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.6,"severity":"HIGH"}],"references":["https://support.broadcom.com/external/content/SecurityAdvisories/0/39077"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-87683","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-87683","identifiers":["CVE-2026-87683"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
