## Technical details

An out-of-bounds read vulnerability exists in Intel PROSet/Wireless WiFi Software's Ring 2 device drivers, which operate with elevated kernel privileges. The flaw can be triggered by a network adversary with adjacent access (e.g., on the same wireless network) without authentication or user interaction, as attack complexity is low. Exploitation can result in escalation of privilege and impacts to system confidentiality and availability. Intel has released software updates to mitigate this issue as of August 2026.
