CVE-2019-16275: Medium severity w1.fi hostapd vulnerability

Published Sep 12, 2019
·
Updated

hostapd before 2.10 and wpasupplicant 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.
