## Description

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Fix memory leak in get_file_all_info() In get_file_all_info(), if vfs_getattr() fails, the function returns immediately without freeing the allocated filename, leading to a memory leak. Fix this by freeing the filename before returning in this error case.
