Headless Linux servers/VMs do not run desktop Firefox or perform browser‑based signing, and EM measurement cannot be performed remotely, so there is no practical network path to exploit this in managed enterprise deployments. With impact limited to confidentiality of a browser‑resident key (no integrity or availability effect), this can be safely deprioritized for server/VM fleets.",
