The vulnerability exists because the affected device does not properly validate 802.11w PAF disassociation and deauthentication frames that it receives. An attacker could exploit this vulnerability by sending a spoofed 802.11w PAF frame from a valid, authenticated client on an adjacent network to an affected device. A successful exploit could allow the attacker to terminate a single valid user connection to the affected device. This vulnerability affects Access Points that are configured to run in FlexConnect mode.
