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

Description A memory leak exists when using the debugfs lookup() function in the Linux kernel’s power management (PM) subsystem, specifically within the embedded memory (EM) component. Failing to call dput() on the result of debugfs lookup() leads to a memory leak over time. The issue is addressed by using debugfs lookup and remove() which handles the necessary memory management logic.

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