CVE-2026-42011

CVE-2026-42011: In GnuTLS, permitted name constraints can be ignored when previous CAs had only excluded constraints, enabling bypass of name-constraint validation. This could allow accepting invalid certificates, potentially allowing spoofing or MITM. No patch/version details are provided in the...

CVE-2026-42011

A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities CAs only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate...
