CVE-2017-13084
Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Station-To-Station-Link (STSL) Transient Key (STK) during the PeerKey handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames.
Does this matter?
Lower severity and a low EPSS score (2.21%). Track it; it rarely justifies an emergency change on its own.
