https://notcve.org/view.php?id=CVE-2022-49915
01 May 2025 — In the Linux kernel, the following vulnerability has been resolved: mISDN: fix possible memory leak in mISDN_register_device() Afer commit 1fa5ae857bb1 ("driver core: get rid of struct device's bus_id string array"), the name of device is allocated dynamically, add put_device() to give up the reference, so that the name can be freed in kobject_cleanup() when the refcount is 0. Set device class before put_device() to avoid null release() function WARN message in device_release(). • https://git.kernel.org/stable/c/1fa5ae857bb14f6046205171d98506d8112dd74e •

However, after a channel is created, the hold operation of the channel is not performed. In this case, the value of channel reference counting is 1.
