      <title>CVE-2023-53588 — wifi: mac80211: check for station first in client probe</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2023-53588</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: check for station first in client probe&lt;/p&gt;
&lt;p&gt;When probing a client, first check if we have it, and then
check for the channel context, otherwise you can trigger
the warning there easily by probing when the AP isn&amp;#39;t even
started yet. Since a client existing means the AP is also
operating, we can then keep the warning.&lt;/p&gt;
&lt;p&gt;Also simplify the moved code a bit.&lt;/p&gt;</description>
