CVE-2023-53409

What is CVE-2023-53409?

The Linux kernel has been updated to fix a memory leak issue related to the debugfs_lookup() function. Without proper handling through dput(), memory allocations can accumulate over time, leading to increased memory usage. To address this, users are advised to utilize debugfs_lookup_and_remove(), which automatically manages memory lifecycle appropriately. It is crucial for administrators and developers to ensure they are using the latest version of the Linux kernel to prevent potential memory-related issues.
