Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)

Description: The issue is related to a dentry leak in the update sched domain debugfs function. This leak occurs when using debugfs remove(debugfs lookup()), which can lead to memory exhaustion under a hotplug stress test. The problem is resolved by using the debugfs lookup and remove() call instead, which properly handles dentry reference counting logic.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
