With the standard contiguous packet-pool layout, a masked server frame split across two packets therefore drives the XOR loop through the first packet's unused payload area and on through the second packet's `NX_PACKET` control block.\n\n\n\nThe four-byte WebSocket masking key controls the bytes written, so the corruption is attacker-chosen rather than incidental.","categories":["Unclassified"],"product":"NetX Duo","vendor":"Eclipse Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102761","source_modified_at":"2026-09-30T20:41:01.935Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"NetX Duo","vendor":"Eclipse Foundation","versions":[{"status":"affected","version":"6.2.0","lessThanOrEqual":"6.5.1.202602","versionType":"semver"},{"status":"unaffected","version":"6.5.2.202603"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":9.3,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00253,"percentile":0.15848,"score_date":"2026-10-23"},"published_at":"2026-09-29T17:30:45.499Z","modified_at":"2026-09-30T20:41:01.935Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-102761","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T20:41:01.935Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-102761","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/eclipse-threadx/netxduo/security/advisories/GHSA-6xgx-v7gw-qjph"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"total","assessed_at":"2026-09-30T20:40:47.914262Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-30T20:41:01.935Z","content_hash":"6f3397cdbd4c8a783bfff7ddfd6e7d491af8f5b9bf0b199201f63bb96268a23e"}}
