      <title>CVE-2022-49442 — drivers/base/node.c: fix compaction sysfs file leak</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2022-49442</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;drivers/base/node.c: fix compaction sysfs file leak&lt;/p&gt;
&lt;p&gt;Compaction sysfs file is created via compaction_register_node in
register_node.  But we forgot to remove it in unregister_node.  Thus
compaction sysfs file is leaked.  Using compaction_unregister_node to fix
this issue.&lt;/p&gt;</description>
