A vulnerability in the WPA2 and WPA3 security implementation of Cisco IOS XE Wireless Controller Software for the Cisco Catalyst 9000 Family could allow an unauthenticated, adjacent attacker to cause denial of service (DoS) condition on an affected device. The vulnerability is due to incorrect packet processing during the WPA2 and WPA3 authentication handshake when configured for dot1x or pre-shared key (PSK) authentication key management (AKM) with 802.11r BSS Fast Transition (FT) enabled. An attacker could exploit this vulnerability by sending a crafted authentication packet to an affected device. A successful exploit could cause an affected device to reload, resulting in a DoS condition.
