Problem Description:

When hostapd is used to operate an access point with SAE (Simultaneous Authentication of Equals; also known as WPA3-Personal), an invalid authentication sequence could result in the hostapd process terminating due to a NULL pointer dereference when processing SAE confirm message. This was caused by missing state validation steps when processing the SAE confirm message in hostapd/AP mode.

See for a detailed description of the bug.


All hostapd versions with SAE support (CONFIG_SAE=y in the build configuration and SAE being enabled in the runtime configuration).
