A security flaw was discovered in the nl80211_set_rekey_data() function in
net/wireless/nl80211.c in the Linux kernel through 4.13.3. This function
does not check whether the required attributes are present in a Netlink
request. This request can be issued by a user with the CAP_NET_ADMIN
capability and may result in a NULL pointer dereference and system crash.
