What is CVE-2023-53413?

A memory leak has been identified in the USB module of the Linux kernel due to improper handling of the debugfs_lookup() function. Failing to call dput() on the result from debugfs_lookup() can lead to memory exhaustion over time. It is recommended to use the debugfs_lookup_and_remove() function, which streamlines the process by automatically managing the necessary cleanup operations. This issue could impact overall system stability and performance if left unaddressed.
