openjdk: Improve certification checking (Oracle CPU 2026-07)

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 NAMESAMETYPE, so...

CVE-2026-68420

CVE-2026-68420 concerns the Linux kernel xfrm subsystem. The issue is a stack-out-of-bounds read triggered when an outbound IPsec policy uses optional IPTFS templates, flowing from xfrm_tmpl_resolve_one() and xfrm_state_find() via the outbound path. The fix extends previous checks that blocked op...
