Description

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

wifi: mac80211_hwsim: fix typo in frequency notification

The NAN notification is for 5745 MHz which corresponds to channel 149 and not 5475 which is not actually a valid channel. This could result in a NULL pointer dereference in cfg80211_next_nan_dw_notif.
