Description
In the Linux kernel, the following vulnerability has been resolved: USB: gadget: bcm63xx_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.

Executive Summary

This vulnerability is a memory leak in the Linux kernel's USB gadget bcm63xx_udc driver. It occurs because when calling the function debugfs_lookup(), the returned result is not properly released with dput(), causing memory to leak over time. The fix involves using debugfs_lookup_and_remove() which handles the release automatically.

Impact Analysis

The memory leak caused by this vulnerability can lead to increased memory usage over time, potentially degrading system performance or causing instability in systems using the affected USB gadget driver.
