+	<h1>Problem Description:</h1>
+	<p>Side channel attacks 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.</p>
+	<p>See
+	https://w1.fi/security/2019-1/sae-side-channel-attacks.txt
+	for a detailed description of the bug.</p>
+	<h1>Impact:</h1>
+	<p>All wpa_supplicant and hostapd versions with SAE support
+	(CONFIG_SAE=y in the build configuration and SAE being enabled in
+	the runtime configuration).</p>
