Improper Input Validation in Intel UEFI ImcErrorHandler Enables Privilege Escalation

Publication date: 2026-03-10

Last updated on: 2026-03-10

Assigner: Intel Corporation

Description
Improper input validation in the UEFI ImcErrorHandler module for some Intel(R) reference platforms may allow an escalation of privilege. System software adversary with a privileged user combined with a high 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 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 (none), integrity (none) and availability (none) impacts.

Executive Summary

This vulnerability is caused by improper input validation in the UEFI ImcErrorHandler module on certain Intel reference platforms. It may allow a system software adversary who already has privileged user access, combined with a high complexity attack, to escalate their privileges further. The attack can potentially be carried out locally without special internal knowledge or user interaction.

Impact Analysis

The vulnerability can impact the confidentiality, integrity, and availability of the vulnerable system at a high level. This means an attacker could potentially gain unauthorized access, alter system data or operations, and disrupt system availability. However, the description notes that subsequent impacts on system confidentiality, integrity, and availability are none.
