      <title>CVE-2023-53321 — wifi: mac80211_hwsim: drop short frames</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2023-53321</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;wifi: mac80211_hwsim: drop short frames&lt;/p&gt;
&lt;p&gt;While technically some control frames like ACK are shorter and
end after Address 1, such frames shouldn&amp;#39;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.&lt;/p&gt;</description>
