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

Description A memory leak exists in the kernel/fail function module when using the debugfs lookup() function. 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() instead, which handles the necessary logic.

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