Memory Leak Issue in Linux Kernel Affecting USB Handling

CVE-2023-53410

What is CVE-2023-53410?

A memory leak vulnerability has been identified in how the Linux kernel handles USB devices. Specifically, the issue arises when using the debugfs_lookup() function without appropriately deallocating the memory with dput(), leading to gradual resource depletion over time. This situation can affect system performance and stability. Developers are advised to utilize debugfs_lookup_and_remove(), which combines the lookup and cleanup operations into a single call, thereby preventing memory leaks and ensuring efficient resource management.
