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.

Weakness

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
