CVE-2025-24912Network attack vector

RADIUS authentication denial via premature request removal

Published Mar 12, 2025 · Updated Mar 12, 2025

Premature resource release in hostapd 2.11 and earlier allows man-in-the-middle attackers to disrupt RADIUS authentication. The radius_client_receive function removes a matching request from the pending retransmit list before a response handler validates its authenticator. An attacker able to inject a spoofed response from the RADIUS server before the legitimate reply can force affected Wi-Fi authentication attempts to fail.
