Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> sched/debug: fix dentry leak in update_sched_domain_debugfs<br /> <br /> Kuyo reports that the pattern of using debugfs_remove(debugfs_lookup())<br /> leaks a dentry and with a hotplug stress test, the machine eventually<br /> runs out of memory.<br /> <br /> Fix this up by using the newly created debugfs_lookup_and_remove() call<br /> instead which properly handles the dentry reference counting logic.
