      <title>CVE-2026-90318 — fat: release buffer head after rebuilding parent</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-90318</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;fat: release buffer head after rebuilding parent&lt;/p&gt;
&lt;p&gt;fat_scan_logstart() leaves the matching directory entry&amp;#39;s buffer head in
sinfo.bh for the caller to release, just like fat_scan().&lt;/p&gt;
&lt;p&gt;fat_rebuild_parent() uses the directory entry to rebuild the parent inode
for the nostale_ro NFS export path, but does not release sinfo.bh after a
successful scan.  Release it once fat_build_inode() has consumed the
directory entry data.&lt;/p&gt;</description>
