{"id":"CVE-2026-106464","details":"`_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.","aliases":["GHSA-ww3q-3444-q488"],"modified":"2026-10-15T10:47:31.426370027Z","published":"2026-10-14T17:41:43.585Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/106xxx/CVE-2026-106464.json","cna_assigner":"eclipse","cwe_ids":["CWE-125","CWE-191"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/106xxx/CVE-2026-106464.json"},{"type":"ADVISORY","url":"https://github.com/eclipse-threadx/netxduo/security/advisories/GHSA-ww3q-3444-q488"},{"type":"WEB","url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/368"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-106464"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/eclipse-threadx/netxduo","events":[{"introduced":"0"},{"last_affected":"ff27569d194f24d296452e1a884d3424f5bb39c9"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"6.5.2.202603"}]}}],"versions":["v6.5.2.202603a_rel","untagged-8ce20f6a594ac40f0829","v6.5.2.202603_rel","v6.4.1_rel","v6.5.1.202602_rel","v6.5.0.202601_rel","v6.4.5.202504_rel","v6.4.4.202503a","v.6.4.4.202503_rel","v6.4.3_rel","v6.4.2_rel","v6.4.0_rel","v6.3.0_rel","v6.2.1_rel","v6.2.0_rel","v6.1.12_rel","v6.1.11_rel","v6.1.10_rel","v6.1.9_rel","v6.1.8_rel","v6.1.7_rel","v6.1.6_rel","v6.1.5_rel","v6.1.4_rel","v6.1.3_rel","v6.1.2_rel","v6.1_rel","v6.0.2_rel","v6.0.1_rel","v6.0_rel"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-106464.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
