Firmware (microcode) mitigations for affected Intel processors have been available since February 2022, and there is no evidence of active exploitation. In centrally managed enterprise VM/server contexts, the need for a pre-existing local foothold combined with a confidentiality-only outcome makes this a lower operational risk.",
