In the Linux kernel, the following vulnerability has been resolved:
smb/server: call ksmbd_proc_cleanup() on module init failure
When a later initializer fails, the unwind chain releases resources
created after procfs and then jumps directly to class_unregister().
Returning an error from module_init() leaves the proc tree and its
per-CPU counters allocated.
