CVE-2026-23142

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mm/damon/sysfs-scheme: cleanup access_pattern subdirs on scheme dir setup failure<br /> <br /> When a DAMOS-scheme DAMON sysfs directory setup fails after setup of<br /> access_pattern/ directory, subdirectories of access_pattern/ directory are<br /> not cleaned up. As a result, DAMON sysfs interface is nearly broken until<br /> the system reboots, and the memory for the unremoved directory is leaked.<br /> <br /> Cleanup the directories under such failures.
