Executive Summary

This vulnerability exists in MAE and is caused by a missing bounds check that leads to a possible out of bounds write.

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

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

User interaction is not required to exploit this vulnerability.

Impact Analysis

If exploited, this vulnerability could allow an attacker who already has System privilege to escalate their privileges further on the local system.

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