In the Linux kernel, the following vulnerability has been resolved:
mm/damon/sysfs-scheme: cleanup accesspattern subdirs on scheme dir setup failure
When a DAMOS-scheme DAMON sysfs directory setup fails after setup of accesspattern/ directory, subdirectories of accesspattern/ 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.
