{"schema":"threatline.record/2","record":{"id":"CVE-2026-92853","aliases":["GHSA-893m-9g4r-4992"],"summary":"Out-of-bounds Read via a Zero-length TLS 1.3 Certificate Message in NetX Secure","details":"The TLS 1.3 Certificate-message parser in NetX Secure decrements the message length to skip a context byte without first establishing that the message has a byte to skip. A zero-length Certificate message therefore wraps the unsigned length to `0xFFFFFFFF`, which makes the bounds check that follows vacuous and sends the parser reading past the session packet buffer.\n\n\n\nThe trigger is a four-byte handshake header and requires no cryptographic validity. It is reachable pre-authentication.","categories":["Unclassified"],"product":"Eclipse ThreadX - NetX Duo","vendor":"Eclipse Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92853","source_modified_at":"2026-10-20T17:02:19.980Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Eclipse ThreadX - NetX Duo","vendor":"Eclipse Foundation","versions":[{"lessThanOrEqual":"6.5.1.202602","status":"affected","version":"0","versionType":"semver"},{"status":"unaffected","version":"6.5.2.202603"}],"defaultStatus":"unaffected"},{"source":"GitHub Advisory Database","source_url":"https://github.com/eclipse-threadx/netxduo/security/advisories/GHSA-893m-9g4r-4992","source_modified_at":"2026-10-02T18:44:45Z","fetched_at":"2026-10-24T14:26:37.433577Z","package":{"ecosystem":"eclipse threadx","name":"NetX Duo"},"range":"<= 6.5.1.202602"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/eclipse-threadx/netxduo/security/advisories/GHSA-893m-9g4r-4992","source_modified_at":"2026-10-02T18:44:45Z","fetched_at":"2026-10-24T14:26:37.433577Z","package":{"ecosystem":"eclipse threadx","name":"NetX Duo"},"version":"6.5.2.202603"}],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00297,"percentile":0.21235,"score_date":"2026-10-23"},"published_at":"2026-10-20T15:10:08.102Z","modified_at":"2026-10-20T17:02:19.980Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-92853","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-20T17:02:19.980Z"},{"source":"GitHub Advisory Database","url":"https://github.com/eclipse-threadx/netxduo/security/advisories/GHSA-893m-9g4r-4992","fetched_at":"2026-10-24T14:26:37.433577Z","source_modified_at":"2026-10-02T18:44:45Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-92853","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/eclipse-threadx/netxduo/security/advisories/GHSA-893m-9g4r-4992"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-20T17:02:10.102886Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-20T17:02:19.980Z","content_hash":"10a6967df6f737cfaefd6cb7e2e66d02a7f59c39cddafcfbba080c0390f47e19"}}
