CVE-2023-53321

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211_hwsim: drop short frames While technically some control frames like ACK are shorter and end after Address 1, such frames shouldn't be forwarded through wmediumd or similar userspace, so require the full 3-address header to avoid accessing invalid memory if shorter frames are passed in.
