CVE-2019-13377 is fixed in 3 products on 1 platform, first by hostapd 2:2.6-15ubuntu2.4, released August 7, 2019. It is not reported as exploited. Patch Radar priority: Routine.
The implementations of SAE and EAP-pwd in hostapd and wpa_supplicant 2.x through 2.8 are vulnerable to side-channel attacks as a result of observable timing differences and cache access patterns when Brainpool curves are used. An attacker may be able to gain leaked information from a side-channel attack that can be used for full password recovery.
