      <title>CVE-2026-89837 — f2fs: fix dentry folio leak in find_in_level</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-89837</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;f2fs: fix dentry folio leak in find_in_level&lt;/p&gt;
&lt;p&gt;find_in_level() gets a dentry folio with f2fs_find_data_folio() before
calling find_in_block().  If find_in_block() returns an error, the
function stores the error in res_folio and breaks out of the loop without
dropping the dentry folio.&lt;/p&gt;
&lt;p&gt;This leaks the folio reference on the find_in_block() error path.  Drop
the dentry folio before returning the error to the caller.&lt;/p&gt;</description>
