In the Linux kernel, the following vulnerability has been resolved: sched/debug: fix dentry leak in updatescheddomaindebugfs Kuyo reports that the pattern of using debugfsremovedebugfslookup leaks a dentry and with a hotplug stress test, the machine eventually runs out of memory. Fix this up by...

CVE-2022-48699

The CVE-2022-48699 issue affects the Linux kernel sched/debug path, where a dentry is leaked by using debugfs_remove(debugfs_lookup()) in update_sched_domain_debugfs. The root cause is improper dentry reference counting, which can, under hotplug stress, lead to memory exhaustion. The available fi...
