Instead, it applies only to organizations with machines that boot from local networks, or conceivably from Internet-connected resources. Even then, the targeted firmware must rely on EDK2, as opposed to a different reference implementation, and use the PXE functionality (which is turned on by default).<\/p>\n<p>In an email, Intel said that none of its \u201ccommercial products currently under security support\u201d are known to be affected. \u201cIntel does not include the affected EDK2 functionality in its reference code, though it may be integrated by an OEM board vendor or system manufacturer,\u201d the company added. It advised customers to check with their system manufacturer for specific guidance. Publicly available <a href=\"https:\/\/github.com\/intel\/FSP\" rel=\"nofollow noopener\" target=\"_blank\">Intel reference code<\/a>, however, makes reference to EDK2. Further, TianoCore <a href=\"https:\/\/www.tianocore.org\/tianocore-wiki.github.io\/reference\/faqs-glossaries\/differences_between_udk_and_edk_ii.html\" rel=\"nofollow noopener\" target=\"_blank\">has said<\/a> that each Intel-supplied UEFI development kit \u201cis a fully validated implementation\u2026 for a specific revision of the EDK II source.\u201d Many other Intel documents reference EDK2 as well.<\/p>\n<p>Arm, meanwhile, responded to a list of questions with: \u201cCVE-2026-97631 is not directly applicable to Arm\u2019s product portfolio.\u201d Like Intel, <a href=\"https:\/\/github.com\/ARM-software\/arm-systemready\/blob\/main\/SystemReady-band\/README.md\" rel=\"nofollow noopener\" target=\"_blank\">firmware<\/a> the company <a href=\"https:\/\/github.com\/ARM-software\/arm-systemready\/blob\/main\/SystemReady-band\/README.md\" rel=\"nofollow noopener\" target=\"_blank\">makes<\/a> available also borrows heavily from EDK2.

Without concrete answers to questions about the use of EDK2 by organizations like these, it\u2019s impossible to say what or how devices are affected and what actions, if any, these organizations, or their users, should take.
