Executive Summary

This vulnerability is an out of bounds write in the wlan AP driver caused by an incorrect bounds check. It can lead to local escalation of privilege if a malicious actor already has System privilege and the OceReducedNeighborReport feature is disabled. Exploitation does not require user interaction.

Impact Analysis

The vulnerability can allow a malicious actor with existing System privilege to escalate their privileges locally, potentially gaining higher control over the affected system. This could lead to unauthorized actions or system compromise.

Mitigation Strategies

Apply the patch identified as WCNCR00441511 to the wlan AP driver to fix the out of bounds write issue. Additionally, ensure that the OceReducedNeighborReport feature is enabled to reduce the risk of exploitation.
