Attack-Flow Graph

Executive Summary

This vulnerability is an out of bounds write in the wlan STA driver caused by an incorrect bounds check. It allows an attacker with user execution privileges to escalate their privileges locally 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 on the affected system, potentially compromising system security.
