When parsing uploaded X.509 PEM certificates for management display, the system improperly validates the length of the Authority Key Identifier (AKI) extension before copying string tokens into an internal memory buffer. An authenticated user with administrative privileges to import custom certificates can supply a certificate containing an intentionally oversized AKI extension. When the system processes or renders the certificate attributes, this can trigger a stack memory corruption leading to a denial-of-service (DoS) condition by crashing the management daemon.","state":0,"publishedAt":"2026-10-08T02:36:55.431+00:00","modifiedAt":"2026-10-08T13:09:01.037+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:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":6.9,"severity":"MEDIUM"}],"references":["https://support.broadcom.com/external/content/SecurityAdvisories/0/39082"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-87676","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-87676","identifiers":["CVE-2026-87676"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
