CVE-2022-26047

Adjacent wireless service interruption

Published Nov 11, 2022 · Updated Jan 29, 2025

Improper input validation in Intel Wi-Fi firmware allows attackers to interrupt wireless service through adjacent access. Intel has not disclosed the input, firmware routine, or validation error that triggers the denial of service. Exploitation requires access to the target's wireless vicinity and affects availability only; the advisory does not specify whether the failure causes a hang, crash, or reboot.
