{"schema":"threatline.record/2","record":{"id":"CVE-2026-82943","aliases":[],"summary":"Out-of-Bounds Read via Unchecked Length Values","details":"SOEM version 2.0.0 and earlier contains vulnerabilities where a malicious device can send messages that cause the master to read data from memory locations beyond the intended buffer. The software uses length values from device responses without validating them against actual buffer sizes. An attacker can exploit this to extract up to 64KB of data from the master's memory.","categories":["Unclassified"],"product":"SOEM","vendor":"RT-Labs AB","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-82943","source_modified_at":"2026-10-26T08:41:26.457Z","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-2026-82943","source_modified_at":"2026-10-26T08:41:26.457Z","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":"2026-10-26T08:41:26.457Z","modified_at":"2026-10-26T08:41:26.457Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-82943","fetched_at":"2026-10-26T12:48:13.248886Z","source_modified_at":"2026-10-26T08:41:26.457Z"}],"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":"2026-10-26T08:41:26.457Z","content_hash":"a1433c65c0bdbc5efe3ed4cef42cacb550c491e9454433cced0c6cf648724c10"}}
