This page contains facts from public vulnerability sources. Check the original advisory before updating.

The implementations of SAE in hostapd and wpa_supplicant are vulnerable to side channel attacks as a result of observable timing differences and cache access patterns.

Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.7 are affected.
