Executive Summary

This vulnerability is a possible escalation of privilege in the display component caused by a missing bounds check.

It means that if a malicious actor already has System privilege, they could exploit this flaw to gain higher privileges locally without needing any user interaction.

Impact Analysis

The impact of this vulnerability is a local escalation of privilege, allowing an attacker who already has System privileges to potentially increase their level of access or control on the affected system.

Since no user interaction is needed, exploitation could be stealthy and increase the risk of unauthorized actions or system compromise.
