## Description

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.
