      <title>CVE-2026-80535 — xfs: don't double-lock when deleting a self-referential directory</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-80535</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;xfs: don&amp;#39;t double-lock when deleting a self-referential directory&lt;/p&gt;
&lt;p&gt;LOLLM notices that the dirtree scrubber can detect a directory that
refers to itself.  In this case, it&amp;#39;s not correct for the directory tree
repair code to try to iolock/ilock both sc-&amp;gt;ip and dp, because they&amp;#39;re
the same inode.  Fix this by detecting that corner case and handling it
appropriately.&lt;/p&gt;</description>
