SUSE CVE-2026-34610

The leancrypto library is a cryptographic library that exclusively contains only PQC-resistant cryptographic algorithms. Prior to version 1.7.1, lcx509extractnamesegment casts sizet vlen to uint8t when storing the Common Name CN length. An attacker who crafts a certificate with CN = victim's CN +...

CVE-2026-34610

A flaw was found in the leancrypto cryptographic library. A remote attacker can exploit an integer overflow vulnerability in the lcx509extractnamesegment function when processing the Common Name CN field of an X.509 certificate. By crafting a specially designed certificate, an attacker can cause...

CVE-2026-34610

The CVE affects leancrypto's PQC-focused crypto library. Before 1.7.1, lc_x509_extract_name_segment() truncates size_t vlen to uint8_t for CN length, allowing an attacker to craft a certificate whose CN impersonates the victim’s CN during PKCS#7 verification, certificate chain matching, and code ...
