In the Linux kernel, the following vulnerability has been resolved:

wifi: virt_wifi: avoid reporting connection success with wrong SSID

When user issues a connection with a different SSID than the one
virt_wifi has advertised, the __cfg80211_connect_result() will
trigger the warning: WARN_ON(bss_not_found).

The issue is because the connection code in virt_wifi does not
check the SSID from user space (it only checks the BSSID), and
virt_wifi will call cfg80211_connect_result() with WLAN_STATUS_SUCCESS
even if the SSID is different from the one virt_wifi has advertised.
Eventually cfg80211 won't be able to find the cfg80211_bss and generate
the warning.

Fixed it by checking the SSID (from user space) in the connection code.
