In the Linux kernel, the following vulnerability has been resolved:
mac80211: fix skb length check in ieee80211_scan_rx() Replace hard-coded
compile-time constants for header length check with dynamic determination
based on the frame type. Otherwise, we hit a validation WARN_ON in cfg80211
later. [style fixes, reword commit message]
