PatchTheCVECVE-2022-37660: In hostapd 2.10 and earlier, the PKEX code remains active even after a successful PKEX association
CVE-2022-37660 is a medium-severity flaw (CVSS 6.5) affecting hostapd. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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 require
