A number of potential side channel attacks were discovered in the SAE implementations used by both hostapd (AP) and wpa_supplicant (infrastructure BSS station/mesh station). SAE (Simultaneous Authentication of Equals) is also known as WPA3-Personal. The discovered side channel attacks may be able to leak information about the used password based on observable timing differences and cache access patterns. This might result in full password recovery when combined with an offline dictionary attack and if the password is not strong enough to protect against dictionary attacks.
