  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm/damon/sysfs: cleanup attrs subdirs on context dir setup failure\n\nWhen a context DAMON sysfs directory setup is failed after setup of attrs/\ndirectory, subdirectories of attrs/ directory are not cleaned up.  As a\nresult, DAMON sysfs interface is nearly broken until the system reboots,\nand the memory for the unremoved directory is leaked.\n\nCleanup the directories under such failures.",
