"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nfirmware: arm_scmi: Quiesce notifications before teardown\n\nscmi_notification_exit() clears and releases the notification instance,\nbut transport callbacks can still deliver incoming notifications until\nthe TX/RX channels are freed. During remove, an RX interrupt in that\nwindow can enter scmi_notify() while notification state is being torn\ndown and then dereference freed memory. The same ordering exists on the\nprobe error path after notification initialization.\n\nThe notification late-init worker has a separate lifetime issue: protocol\nevent registration queues ni->init_work on the system workqueue, so\ndestroying ni->notify_wq does not drain that work. If the devres group is\nreleased while init_work is still pending or running, the late-init worker\ncan dereference the freed notification instance.\n\nQuiesce the notification core before TX/RX channels are torn down, then\nclean up the channels before releasing the notification core resources.\nUse disable_work_sync() so future late-init queueing is rejected and any\nalready queued or running late-init work has completed before channel\nteardown starts."
