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

Description A memory leak exists in the USB gadget pxa27x udc driver when using the debugfs lookup() function. The dput() function was not called on the result of debugfs lookup(), leading to a memory leak over time. The issue is addressed by using debugfs lookup and remove() instead, which handles the necessary memory management logic.
