How to fix?

NVD Description

Note: Versions mentioned in the description apply only to the upstream wpa package and not the wpa package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

An invalid authentication sequence could result in the hostapd process terminating due to missing state validation steps when processing the SAE confirm message when in hostapd/AP mode. All version of hostapd with SAE support are vulnerable. An attacker may force the hostapd process to terminate, performing a denial of service attack. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.7 are affected.
