CVE-2019-16275
First published: Thu Sep 12 2019(Updated: )
hostapd before 2.10 and wpa_supplicant before 2.10 allow an incorrect indication of disconnection in certain situations because source address validation is mishandled. This is a denial of service that should have been prevented by PMF (aka management frame protection). The attacker must send a crafted 802.11 frame from a location that is within the 802.11 communications range. An attacker in radio range of the access point could inject a specially constructed unauthenticated IEEE 802.11 frame to the access point to cause associated stations to be disconnected and require a reconnection to the network.
