CVE-2023-53405
USB: gadget: gr_udc: fix memory leak with using debugfs_lookup()
Description

In the Linux kernel, the following vulnerability has been resolved: USB: gadget: gr_udc: fix memory leak with using debugfs_lookup() When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once.

Solution
Fix memory leak by using debugfs_lookup_and_remove() instead of debugfs_lookup().
  • Replace debugfs_lookup() calls with debugfs_lookup_and_remove().
  • Ensure dput() is called on debugfs_lookup() results.
  • Apply the patch to resolve the memory leak.
