CVE-2019-16275  (opens in a new tab)
CWE-346  (opens in a new tab)

How to fix?

Upgrade Ubuntu:14.04 wpa to version 2.1-0ubuntu1.7+esm2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream wpa package and not the wpa package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

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.
