How to fix?

Upgrade Ubuntu:20.04 wpa to version 2:2.9-1ubuntu4.6 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:20.04 relevant fixed versions and status.

In hostapd 2.10 and earlier, the PKEX code remains active even after a successful PKEX association. An attacker that successfully bootstrapped public keys with another entity using PKEX in the past, will be able to subvert a future bootstrapping by passively observing public keys, re-using the encrypting element Qi and subtracting it from the captured message M (X = M - Qi). This will result in the public ephemeral key X; the only element required to subvert the PKEX association.
