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).","state":0,"publishedAt":"2026-10-08T03:00:54.306+00:00","modifiedAt":"2026-10-08T13:46:29.7+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:H/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","score":6.9,"severity":"MEDIUM"}],"references":["https://support.broadcom.com/external/content/SecurityAdvisories/0/39152"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-87668","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-87668","identifiers":["CVE-2026-87668"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
