Executive Summary

This vulnerability is 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 memory area it is supposed to, which can corrupt memory and lead to unexpected behavior.

In this case, the vulnerability could allow a local attacker who already has System privilege to escalate their privileges further.

No user interaction is needed to exploit this vulnerability.

Impact Analysis

If exploited, this vulnerability could allow a malicious actor with existing System privileges to escalate their privileges locally.

This means the attacker could gain higher-level access or control over the affected system, potentially leading to unauthorized actions or system compromise.

Since no user interaction is needed, the exploitation could be stealthy and automated once the attacker has System privileges.
