Description (CNA)
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. An attacker may be able to gain leaked information from a side channel attack that can be used for full password recovery. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.7 are affected.
Affected (CNA)
| Vendor / product | Versions |
|---|---|
| Wi-Fi Alliance / hostapd with SAE support | affected 2.7 through 2.7 |
| Wi-Fi Alliance / wpa_supplicant with SAE support | affected 2.7 through 2.7 |
CWE
