CVE-2026-60147

A flaw was found in OpenJDK. OpenJDK can apply two different security meanings to the same wildcard dNSName SAN across certificate policy enforcement and hostname verification. During path validation, DNSName.constrains compares *.foo.com and secret.foo.com literally and returns NAME_SAME_TYPE, so NameConstraintsExtension.verify does not reject the chain when secret.foo.com is an exact-host exclusion. Later, HostnameChecker interprets the same SAN as a wildcard template and accepts secret.foo.com for *.foo.com.
