The USBX host recorded that figure and used it as the budget for walking the format, frame and frame-interval descriptors, without holding it against the configuration descriptor actually received.\n\n\n\nA device that reports a `wTotalLength` larger than the descriptors it supplies therefore had its own claim believed. Once the real bytes ran out the walk kept going, dereferencing the cursor past the end of the configuration buffer, in the host's context, whenever the application queried format or frame data.","state":0,"publishedAt":"2026-10-20T13:17:37.426+00:00","modifiedAt":"2026-10-20T15:28:49.518+00:00","affected":[{"ecosystem":"Vendor product","name":"USBX","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Eclipse Foundation\",\n                    \"product\": \"Eclipse ThreadX -  USBX\",\n                    \"packageName\": \"USBX\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"6.5.1.202602\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"6.5.2.202603\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","score":4.9,"severity":"MEDIUM"}],"references":["https://github.com/eclipse-threadx/usbx/security/advisories/GHSA-8qf6-hjvf-g68f"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-96406","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-96406","identifiers":["CVE-2026-96406"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
