Description
A vulnerability in the 802.11 association frame validation of Cisco Catalyst 9100 Series Access Points (APs) could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of certain parameters within association request frames received by the AP. An attacker could exploit this vulnerability by sending a crafted 802.11 association request to a nearby device. An exploit could allow the attacker to unexpectedly reload the device, resulting in a DoS condition.
