Attack-Flow Graph

Executive Summary

This vulnerability is an out of bounds write in the wlan AP driver caused by an incorrect bounds check. It allows an attacker with local user execution privileges to escalate their privileges on the system without needing any user interaction.

Impact Analysis

The vulnerability can lead to local escalation of privilege, meaning an attacker who already has user-level access could gain higher privileges, potentially compromising the security and integrity of the affected system.
