Security update for wpa_supplicant

This update for wpa_supplicant fixes the following issues:

  • CVE-2025-24912: hostapd RADIUS authentication of wi-fi devices allows a user in between the hostapd and the RADIUS server to inject crafted RADIUS packets and force RADIUS authentications to fail (bsc#1239461).
  • CVE-2026-58374: missing bounds check in AP-mode Wi-Fi 7 (IEEE 802.11be) MLO association request processing allows an unauthenticated user to send a crafted management frame and cause an out-of-bounds write (bsc#1269892).
  • Missing network context validation for PMKSA caching https://w1.fi/security/2026-2/
  • Unexpected SAE commit message contents terminating wpa_supplicant https://w1.fi/security/2026-3/

Описание

hostapd fails to process crafted RADIUS packets properly. When hostapd authenticates wi-fi devices with RADIUS authentication, an attacker in the position between the hostapd and the RADIUS server may inject crafted RADIUS packets and force RADIUS authentications to fail.

Описание

In hostapd before 2.12, a missing bounds check in AP-mode Wi-Fi 7 (IEEE 802.11be) Multi-Link Operation (MLO) association request processing allows an unauthenticated attacker within wireless range to send a crafted management frame containing a malformed Multi-Link Element or Per-STA Profile subelement. In hostapd_process_ml_assoc_req() in src/ap/ieee802_11_eht.c, the received link_id field can be parsed as value 15, but the corresponding links[] storage only has valid entries for lower link IDs (0 through 14). This causes an out-of-bounds write / small memory corruption during association processing before the 4-way handshake. The attack does not require network credentials, prior authentication, or user interaction. The confirmed practical impact is denial of service through hostapd process termination. This affects hostapd v2.11 and newer development snapshots before v2.12 when built with CONFIG_IEEE80211BE enabled. The issue is fixed in hostapd v2.12 and the upstream 2026-1 fixes.
