When processing an incoming SNMPv3 packet, an internal statistics gathering handler copies user-supplied context name data into a fixed-size buffer without properly validating the length of the string. A remote, unauthenticated attacker (under default configuration) can exploit this vulnerability by sending a specially crafted SNMPv3 packet, leading to memory corruption, daemon crash (Denial of Service), or potential arbitrary code execution.","state":0,"publishedAt":"2026-10-08T02:18:19.519+00:00","modifiedAt":"2026-10-08T17:57:21.68+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:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"}],"references":["https://support.broadcom.com/external/content/SecurityAdvisories/0/39078"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-87684","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-87684","identifiers":["CVE-2026-87684"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
