The lower level nl80211 code in cfg80211 ensures that "len" is between
25 and NL80211_ATTR_FRAME (2304). We subtract DOT11_MGMT_HDR_LEN (24) from
"len" so thats's max of 2280. However, the action_frame->data[] buffer is
only BRCMF_FIL_ACTION_FRAME_SIZE (1800) bytes long so this memcpy() can
overflow.
memcpy(action_frame->data, &buf[DOT11_MGMT_HDR_LEN],
le16_to_cpu(action_frame->len));
