Intel Server Board / Server System / Compute Module platform firmware: Improper memory initialisation in platform

Impact

Improper memory initialisation in platform sample/silicon reference firmware on Intel server boards, allowing privilege escalation. Reference firmware defects propagate into whatever the OEM built on top of it, so the affected population is wider than Intel-branded boards.

Who can reach it

Privileged local access on the host.

What to do

Fixed in platform BIOS/UEFI firmware. That means an OEM release, a per-node drain, a flash and a cold reboot - and OEM availability commonly lags the Intel advisory by quarters on server boards. There is no microcode or OS-level shortcut for this class; budget it as a fleet-wide maintenance campaign, not a patch.
