Executive Summary

This vulnerability involves a possible out of bounds write in the display component caused by a missing bounds check.

An out of bounds write means that the software writes data outside the allocated memory buffer, which can corrupt memory and lead to unexpected behavior.

Exploitation of this vulnerability could allow a malicious actor who already has System privilege to escalate their privileges locally.

No user interaction is required to exploit this vulnerability.

Impact Analysis

If exploited, this vulnerability could allow an attacker with existing System privileges to escalate their privileges further on the affected system.

This could lead to greater control over the system, potentially allowing the attacker to execute unauthorized actions or access sensitive information.

Since no user interaction is needed, the vulnerability could be exploited silently once the attacker has System privileges.
