Authentication rejection was found when doing fuzz testing even with a valid SAE commit message when it was sent after a SAE commit message that included an incorrect password identifier. The test steps for this are as below: 1. Peer sends an abnormal commit message with incorrect password identifier 2. APUT rejects as expected 3. Peer sends a valid commit message 4. APUT rejects again, which is not expected In step 2, as the abnormal data fakes an empty password identifier element, it passes sae_is_password_id_elem() checking. Memory is then allocated for sae->tmp->pw_id. The authentication process then fails due to no available password with this invalid password identifier. In step 4, though the peer sends a valid commit message, APUT rejects this SAE commit again due to no password identifier element (due to that sae->tmp->pw_id being set), which is not expected. Free the sae->tmp->pw_id field and set it to NULL when SAE commit message processing fails due to an unknown password identifier so that the bogus value is not used as a requirement for any consecutive SAE commit from the same STA before the STA entry gets cleared.

wpa_supplicant and hostapd -------------------------- Copyright (c) 2002-2022, Jouni Malinen <j@w1.fi> and contributors All Rights Reserved. These programs are licensed under the BSD license (the one with advertisement clause removed). If you are submitting changes to the project, please see CONTRIBUTIONS file for more instructions. This package may include either wpa_supplicant, hostapd, or both. See README file respective subdirectories (wpa_supplicant/README or hostapd/README) for more details. Source code files were moved around in v0.6.x releases and compared to earlier releases, the programs are now built by first going to a subdirectory (wpa_supplicant or hostapd) and creating build configuration (.config) and running 'make' there (for Linux/BSD/cygwin builds).
