# Intel server boards: UEFI VGA check can leak memory contents

Link for people: https://infrastack.ai/live/CVE-2026-55716 (this .md is for agents)

A out-of-bounds read in the UEFI firmware routine CheckUefiVgaMode on Intel Server Board D50DNP and M50FCP can expose data from firmware memory. An attacker with privileged local access and a high-complexity setup could read sensitive data.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Identify the board model with `dmidecode -s baseboard-product-name` on the server
- Compare the BIOS/UEFI version against Intel's advisory for D50DNP and M50FCP boards

## From the sources

Out-of-bounds read in the CheckUefiVgaMode for the Intel(R) Server Board D50DNP and Intel(R) Server Board M50FCP within Ring 0 UEFI may allow an information disclosure. Startup code and smm adversary with a privileged user combined with a high complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
