      <title>CVE-2025-21699 — gfs2: Truncate address space when flipping GFS2_DIF_JDATA flag</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2025-21699</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;gfs2: Truncate address space when flipping GFS2_DIF_JDATA flag&lt;/p&gt;
&lt;p&gt;Truncate an inode&amp;#39;s address space when flipping the GFS2_DIF_JDATA flag:
depending on that flag, the pages in the address space will either use
buffer heads or iomap_folio_state structs, and we cannot mix the two.&lt;/p&gt;</description>
