Memory Leak Vulnerability in Linux Kernel Affecting Debugfs Operations

CVE-2023-53403

What is CVE-2023-53403?

A memory leak vulnerability exists in the Linux kernel related to the debugfs_lookup() function. Failing to invoke dput() on the result of this function can lead to gradual memory consumption over time. To mitigate this issue easily, developers are advised to use debugfs_lookup_and_remove(), which integrates the necessary logic to prevent memory leaks. Proper handling of these functions is crucial for maintaining system stability and performance.
