No evidence-backed relationships are recorded.
ShieldCrash, a public proof of concept, reaches SYSTEM-level file reads on fully patched Windows hosts, defeating Microsoft's fix for CVE-2026-69414. Only arbitrary read has been shown, not code execution, and there is no confirmed exploitation in the wild.
