What is CVE-2023-53346?

A vulnerability exists in the Linux kernel related to memory management during the use of the debugfs_lookup() function. Failure to properly release memory associated with this function can lead to memory leaks over time. To mitigate this issue, developers are advised to utilize the debugfs_lookup_and_remove() function, which simplifies the handling of both lookup and memory release, thus preventing potential memory exhaustion and improving overall system stability.
