{"id":"CVE-2026-106464","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-106464","generatedAt":"2026-10-28T00:59:39.350Z","title":"Certificates are parsed from the peer during the TLS handshake, so the input is remote and unauthenticated.","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.","published":"2026-10-14T18:17:25.000Z","lastModified":"2026-10-16T21:17:18.000Z","status":"Awaiting Analysis","sourceIdentifier":"emo@eclipse.org","cvss":{"version":"4.0","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/M"},"cwe":["CWE-125","CWE-191"],"affected":[],"epss":{"score":0.00173,"percentile":0.06704,"date":"2026-10-26","history":[{"date":"2026-10-15","score":0.00181,"percentile":0.07144}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.17%).
