A zero-length Certificate message therefore wraps the unsigned length to `0xFFFFFFFF`, which makes the bounds check that follows vacuous and sends the parser reading past the session packet buffer.\n\n\n\nThe trigger is a four-byte handshake header and requires no cryptographic validity. It is reachable pre-authentication.","state":0,"publishedAt":"2026-10-20T15:10:08.102+00:00","modifiedAt":"2026-10-20T17:02:19.98+00:00","affected":[{"ecosystem":"Vendor product","name":"NetX Duo","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Eclipse Foundation\",\n                    \"product\": \"Eclipse ThreadX - NetX Duo\",\n                    \"packageName\": \"NetX Duo\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"6.5.1.202602\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"6.5.2.202603\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"}],"references":["https://github.com/eclipse-threadx/netxduo/security/advisories/GHSA-893m-9g4r-4992"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92853","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92853","identifiers":["CVE-2026-92853"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
