Description
In the Linux kernel, the following vulnerability has been resolved: mm/damon/sysfs-scheme: cleanup access_pattern subdirs on scheme dir setup failure 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. Cleanup the directories under such failures.
