{"id":"CVE-2026-106464","published":"2026-10-14T18:17:24.960","lastModified":"2026-10-16T21:17:18.010","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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-125","CWE-191"],"vendors":[],"products":[],"references":[{"url":"https://github.com/eclipse-threadx/netxduo/security/advisories/GHSA-ww3q-3444-q488","tags":[]},{"url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/368","tags":[]}],"exploitRefs":[{"url":"https://github.com/eclipse-threadx/netxduo/security/advisories/GHSA-ww3q-3444-q488","tags":[]}],"hasPoc":true,"ai":null}
