Linux · Linux Kernel · CVE-2022-48699
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.
