Memory Leak Vulnerability in Linux Kernel Affecting Debugfs Functionality

CVE-2023-53411

What is CVE-2023-53411?

A memory leak vulnerability exists in the Linux kernel's handling of the debugfs_lookup() function. When this function is called, it is crucial that the result is followed up with a call to dput() to prevent memory from leaking over time. A fix is advised to utilize the debugfs_lookup_and_remove() method instead, which simplifies the process by managing the associated logic effectively, thus mitigating the risk of memory leaks in the kernel.
