Several vulnerabilities have been discovered in wpa_supplicant and
hostapd.
CVE-2020-12695
It was discovered that hostapd does not properly handle UPnP
subscribe messages under certain conditions, allowing an attacker to
cause a denial of service.
CVE-2021-0326
It was discovered that wpa_supplicant does not properly process P2P
(Wi-Fi Direct) group information from active group owners. An
attacker within radio range of the device running P2P could take
advantage of this flaw to cause a denial of service or potentially
execute arbitrary code.
