If it succeeds, pnfs_put_layout_hdr(lo) is called before trace_pnfs_update_layout(), which still references &#39;lo&#39;. This results in a use-after-free when the tracepoint accesses lo&#39;s fields.</p> <p>Fix this by moving the tracepoint call before pnfs_put_layout_hdr(lo).</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>pNFS: Fix use-after-free in pnfs_update_layout()</p> <p>When hitting the NFS_LAYOUT_RETURN branch in pnfs_update_layout(), the code calls pnfs_prepare_to_retry_layoutget(lo).
