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.","score":6.5,"severity":"medium","published":"2026-10-26T08:51:32.194Z","modified":"2026-10-26T14:35:19.284Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"RT-Labs AB","name":"SOEM","platforms":[],"versions":[{"version":"0","status":"affected","lessThan":"2.0.1","versionType":"semver"}],"defaultStatus":"unaffected","cpes":[],"source":"ENISA","url":"https://www.cve.org/CVERecord?id=CVE-2026-82945"}],"remediation":[],"references":["https://rt-labs.com/wp-content/uploads/2026/10/RRTL-260921-01.pdf"],"sources":[{"name":"CVE","id":"CVE-2026-82945","modified":"2026-10-26T14:35:19.284Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-82945"}],"assessments":[{"source":"ENISA","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":6.5}],"sourceAffected":[],"observedAt":"2026-10-29T14:44:38.370Z","kev":{"status":"not-listed","checkedAt":"2026-10-31T09:10:30.844Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":{"text":"SOEM version 2.0.0 and earlier has a memory corruption vulnerability due to an out-of-bounds write when a malicious device presents more configuration blocks than expected.
