NVD Description

Note: Versions mentioned in the description apply only to the upstream wpa package and not the wpa package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

The eap_pwd_perform_confirm_exchange function in eap_peer/eap_pwd.c in wpa_supplicant 2.x before 2.6, when EAP-pwd is enabled in a network configuration profile, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an EAP-pwd Confirm message followed by the Identity exchange.
