Out-of-Bounds Write in Intel Server Board UEFI Firmware

Publication date: 2026-11-10

Last updated on: 2026-11-10

Assigner: Intel Corporation

Description
Out-of-bounds write in the XmlCliCommonDxe for the Intel(R) Server Board D50DNP and Intel(R) Server Board M50FCP within Ring 0 UEFI may allow an escalation of privilege. Startup code and smm adversary with a privileged user combined with a high complexity attack may enable local code execution. 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 (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (high) impacts.

Executive Summary

This is an out-of-bounds write vulnerability in the XmlCliCommonDxe component for Intel Server Board D50DNP and M50FCP within Ring 0 UEFI. It allows a privileged local attacker with startup code or SMM access to execute arbitrary code. The attack requires high complexity and no special internal knowledge or user interaction.

Impact Analysis

An attacker could exploit this to gain local code execution, leading to complete control over the system. This may result in high impacts on confidentiality, integrity, and availability of the affected system, potentially causing data breaches or system compromise.

Mitigation Strategies

Apply firmware updates from Intel for affected Server Board D50DNP and M50FCP systems. Disable unnecessary UEFI features if updates are unavailable. Restrict physical and administrative access to systems to reduce attack surface.
