Incorrect Permission Assignment in Intel SysFwUpdt Enables Privilege Escalation

Publication date: 2026-02-10

Last updated on: 2026-02-10

Assigner: Intel Corporation

Description
Incorrect permission assignment for critical resource for some System Firmware Update Utility (SysFwUpdt) for Intel(R) Server Boards and Intel(R) Server Systems Based before version 16.0.12. within Ring 3: User Applications may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires passive user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Executive Summary

This vulnerability involves incorrect permission assignment in the System Firmware Update Utility (SysFwUpdt) for certain Intel Server Boards and Systems before version 16.0.12. It allows a user application running with high privileges to potentially escalate their privileges further. The attack requires local access, a privileged user, and low complexity, with only passive user interaction needed.

The vulnerability affects the system at Ring 3 (user application level) and may impact the confidentiality, integrity, and availability of the system.

Impact Analysis

This vulnerability can lead to an escalation of privilege, meaning an attacker with some level of access could gain higher privileges than intended. This can compromise the confidentiality, integrity, and availability of the affected system.

  • Confidentiality impact: High
