CVE-2022-48699 is a dentry leak vulnerability in the Linux kernel's scheduler debugfs component, specifically affecting Linux kernel versions. This flaw, categorized as a Medium severity issue (CVSS 5.5), allows a local attacker with low privileges to cause a denial of service (system out of memory) through repeated hotplug stress tests. The vulnerability has no known public exploits, Metasploit modules, or Nuclei templates, and there is no evidence of active exploitation or significant community discussion. The fix involves using debugfs_lookup_and_remove() to correctly handle dentry reference counting.
