Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: drivers/base/node.c: fix compaction sysfs file leak Compaction sysfs file is created via compaction_register_node in register_node. But we forgot to remove it in unregister_node. Thus compaction sysfs file is leaked. Using compaction_unregister_node to fix this issue.
