{"schemaVersion":3,"id":"CVE-2026-106464","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"`_nx_secure_x509_parse_signature_data` computes the certificate signature's length as `tlv_length - 1` without first checking that `tlv_length` is non-zero. A certificate whose signature is an empty ASN.1 BIT STRING therefore parses successfully and leaves the certificate holding a signature length of `0xFFFFFFFF` and a signature pointer one byte past the end of the buffer. Certificates are parsed from the peer during the TLS handshake, so the input is remote and unauthenticated.","dates":{"published":"2026-10-14T17:41:43.585Z","modified":"2026-10-16T20:13:45.214Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.7,"severity":"high","version":"4.0","versionLabel":"v4.0","source":"CVE.org","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":8.7,"severity":"high","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":8.7,"severity":"high","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00181,"percentile":0.07219,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-15T00:00:00.000Z","score":0.00181,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00181,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00181,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00181,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00181,"percentile":0.07219}],"last30":[{"date":"2026-10-15T00:00:00.000Z","score":0.00181,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00181,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00181,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00181,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00181,"percentile":0.07219}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-125","name":"Out-of-bounds Read","description":"The product reads data past the end, or before the beginning, of the intended buffer.","type":"weakness","status":"Draft","abstraction":"Base","likelihoodOfExploit":null,"url":"https://cwe.mitre.org/data/definitions/125.html"},{"id":"CWE-191","name":"Integer Underflow (Wrap or Wraparound)","description":"The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.","type":"weakness","status":"Draft","abstraction":"Base","likelihoodOfExploit":null,"url":"https://cwe.mitre.org/data/definitions/191.html"}],"affected":[{"vendor":"eclipse foundation","product":"netx duo","name":"NetX Duo","label":"netx duo","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"≤ 6.5.2.202603","noFixRecorded":false,"fixedIn":null}],"versionsText":"≤ 6.5.2.202603","eol":null,"hubHref":"/vendor/eclipse_foundation/netx_duo"}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://github.com/eclipse-threadx/netxduo/security/advisories/GHSA-ww3q-3444-q488","label":"github.com/eclipse-threadx/netxduo/security/advisories/GHSA-ww3q-3444-q488","hostname":"github.com","tags":[]},{"url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/368","label":"gitlab.eclipse.org/security/cve-assignment/-/work_items/368","hostname":"gitlab.eclipse.org","tags":[]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-14T17:41:43.585Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-16T20:13:45.214Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":35,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-19T17:03:24.253Z","stale":false,"partial":false}}
