The EAP-pwd server and peer implementation in hostapd and wpa_supplicant 1.0 up to and including 2.4 allows remote malicious users to cause a denial of service (out-of-bounds read and crash) via a crafted (1) Commit or (2) Confirm message payload.

The EAP-pwd server and peer implementation in hostapd and wpa_supplicant 1.0 up to and including 2.4 does not validate that a message is long enough to contain the Total-Length field, which allows remote malicious users to cause a denial of service (crash) via a crafted message.
