      <title>CVE-2026-23142 — mm/damon/sysfs-scheme: cleanup access_pattern subdirs on scheme dir setup failure</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-23142</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;mm/damon/sysfs-scheme: cleanup access_pattern subdirs on scheme dir setup failure&lt;/p&gt;
&lt;p&gt;When a DAMOS-scheme DAMON sysfs directory setup fails after setup of
access_pattern/ directory, subdirectories of access_pattern/ directory are
not cleaned up.  As a result, DAMON sysfs interface is nearly broken until
the system reboots, and the memory for the unremoved directory is leaked.&lt;/p&gt;
&lt;p&gt;Cleanup the directories under such failures.&lt;/p&gt;</description>
