Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: mac80211_hwsim: drop short frames<br /> <br /> While technically some control frames like ACK are shorter and<br /> end after Address 1, such frames shouldn&amp;#39;t be forwarded through<br /> wmediumd or similar userspace, so require the full 3-address<br /> header to avoid accessing invalid memory if shorter frames are<br /> passed in.
