    Added Description In the Linux kernel, the following vulnerability has been resolved:

    module: ensure that kobject_put() is safe for module type kobjects

    In ‘lookup_or_create_module_kobject()’, an internal kobject is created
    using ‘module_ktype’. So call to ‘kobject_put()’ on error handling
    path causes an attempt to use an uninitialized completion pointer in
    ‘module_kobject_release()’. In this scenario, we just want to release
    kobject without an extra synchronization required for a regular module
    unloading process, so adding an extra check whether ‘complete()’ is
    actually required makes ‘kobject_put()’ safe.
