Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Fix slab-use-after-free in scmi_bus_notifier()
The scmi_dev->name is released prematurely in __scmi_device_destroy(), which causes slab-use-after-free when accessing scmi_dev->name in scmi_bus_notifier(). So move the release of scmi_dev->name to scmi_device_release() to avoid slab-use-after-free.
