The software writes configuration data to a fixed-size array without checking if the array index exceeds its maximum size of EC_MAXFMMU entries. A device presenting more than EC_MAXFMMU configuration blocks can force writes beyond the array boundary, corrupting adjacent memory structures and potentially disrupting subsequent operations.","state":0,"publishedAt":"2026-10-26T08:51:32.194+00:00","modifiedAt":"2026-10-26T08:51:32.194+00:00","affected":[{"ecosystem":"Vendor product","name":"SOEM","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"RT-Labs AB\",\n                    \"product\": \"SOEM\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"2.0.1\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":6.5,"severity":"MEDIUM"}],"references":["https://rt-labs.com/wp-content/uploads/2026/10/RRTL-260921-01.pdf"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-82945","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-82945","identifiers":["CVE-2026-82945"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
