Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mwifiex: Do not return unused priv in mwifiex_get_priv_by_id() mwifiex_get_priv_by_id() returns the priv pointer corresponding to the bss_num and bss_type, but without checking if the priv is actually currently in use. Unused priv pointers do not have a wiphy attached to them which can lead to NULL pointer dereferences further down the callstack. Fix this by returning only used priv pointers which have priv->bss_mode set to something else than NL80211_IFTYPE_UNSPECIFIED. Said NULL pointer dereference happened when an Accesspoint was started with wpa_supplicant -i mlan0 with this config: network={ ssid='somessid' mode=2 frequency=2412 key_mgmt=WPA-PSK WPA-PSK-SHA256 proto=RSN group=CCMP pairwise=CCMP psk='12345678' } When waiting for the AP to be established, interrupting wpa_supplicant with
