{"schema":"threatline.record/2","record":{"id":"CVE-2026-82945","aliases":[],"summary":"Memory Corruption via FMMU Configuration Table Overflow","details":"SOEM version 2.0.0 and earlier contains a vulnerability during device configuration where a malicious device can cause memory corruption. 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.","categories":["Unclassified"],"product":"SOEM","vendor":"RT-Labs AB","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-82945","source_modified_at":"2026-10-26T08:51:32.194Z","fetched_at":"2026-10-26T12:48:13.248886Z","product":"SOEM","vendor":"RT-Labs AB","versions":[{"status":"affected","version":"0","lessThan":"2.0.1","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-82945","source_modified_at":"2026-10-26T08:51:32.194Z","fetched_at":"2026-10-26T12:48:13.248886Z","package":{"name":"SOEM","ecosystem":null},"version":"2.0.1","basis":"first unaffected version stated in the CVE record"}],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-26T08:51:32.194Z","modified_at":"2026-10-26T08:51:32.194Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-82945","fetched_at":"2026-10-26T12:48:13.248886Z","source_modified_at":"2026-10-26T08:51:32.194Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://rt-labs.com/wp-content/uploads/2026/10/RRTL-260921-01.pdf","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-26T08:51:32.194Z","content_hash":"929a7a96ab89383437edd98c09e62e49fa169ac063cf394436107b2e59343ef6"}}
