About vulnerability
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Unregister device notifier before IDR teardown
The requested-devices notifier looks up protocol fwnodes from the active_protocols IDR. During remove, unregister the notifier before releasing and destroying active_protocols so no notifier callback can race with the IDR teardown.
Keep the bus notifier registered until after the protocol state is torn down, matching the existing remove ordering for SCMI bus users.
