TDX Security Update 2026.08.11

Four TDX disclosures hit our systems: INTEL-SA-01421, INTEL-SA-01462, INTEL-SA-01419, INTEL-SA-01442. First two don't apply—unused Intel libraries. Last two, affecting TDX Module and microcode, were mitigated pre-disclosure via v1.5.25 and microcode 20260811. BuilderNet is safe; no untrusted privileged users exist. Hosts get patched shortly.
