What is CVE-2018-14526?

A vulnerability in wpa_supplicant versions 2.0 through 2.6 exists where under specific conditions, the integrity verification of EAPOL-Key messages is bypassed. This flaw allows an attacker within proximity of the Access Point and client to exploit the weak validation to create a decryption oracle, potentially recovering sensitive information transmitted over the network. Mitigation measures should be taken to secure systems against potential unauthorized access and data breaches.
