CVE-2026-42011 severity important: SUSE including 10 source package names (gnutls-3.8.13-1.1, libgnutls-dane-devel-3.8.13-1.1, …), 10 product×package rows across 1 product lines (openSUSE Tumbleweed): Fixed 10.
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 validation. This bypass could lead to the acceptance of invalid certificates, potentially enabling spoofing or man-in-the-middle attacks against affected systems.
