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

Description A memory leak exists in the USB UHCI driver 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 memory management logic.

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