CVE-2019-16275wpa_supplicant: AP mode PMF disconnection protection bypass

Description

A vulnerability was discovered in wpa_supplicant. When Access Point (AP) mode and Protected Management Frames (PMF) (IEEE 802.11w) are enabled, wpa_supplicant does not perform enough validation on the source address of some received management frames. An attacker within the 802.11 communications range could use this flaw to inject an unauthenticated frame and perform a denial-of-service attack against another device which would be disconnected from the network.
