Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: wwan_hwsim: fix possible memory leak in wwan_hwsim_dev_new() Inject fault while probing module, if device_register() fails, but the refcount of kobject is not decreased to 0, the name allocated in dev_set_name() is leaked.
