Overview
Affected versions of this package are vulnerable to Off-by-one Error in the hostapd_process_ml_assoc_req function. An attacker can cause process termination and denial of service by sending a crafted management frame containing a malformed Multi-Link Element or Per-STA Profile subelement with an out-of-range link_id value, resulting in an out-of-bounds write during association processing before the 4-way handshake. This is only exploitable if the software is built with CONFIG_IEEE80211BE enabled.
