Title
mailbox: mtk-cmdq: Move devm_mbox_controller_register() after devm_pm_runtime_enable()
Summary
In the Linux kernel, the following vulnerability has been resolved:
mailbox: mtk-cmdq: Move devm_mbox_controller_register() after devm_pm_runtime_enable()
When mtk-cmdq unbinds, a WARN_ON message with condition
pm_runtime_get_sync() < 0 occurs.
According to the call tracei below:
cmdq_mbox_shutdown
mbox_free_channel
mbox_controller_unregister
__devm_mbox_controller_unregister
...
The root cause can be deduced to be calling pm_runtime_get_sync() after
calling pm_runtime_disable() as observed below:
1. CMDQ driver uses devm_mbox_controller_register() in cmdq_probe()
to bind the cmdq device to the mbox_controller, so
devm_mbox_controller_unregister() will automatically unregister
the device bound to the mailbox controller when the device-managed
resource is removed. That means devm_mbox_controller_unregister()
and cmdq_mbox_shoutdown() will be called after cmdq_remove().
2. CMDQ driver also uses devm_pm_runtime_enable() in cmdq_probe() after
devm_mbox_controller_register(), so that devm_pm_runtime_disable()
will be called after cmdq_remove(), but before
devm_mbox_controller_unregister().
To fix this problem, cmdq_probe() needs to move
devm_mbox_controller_register() after devm_pm_runtime_enable() to make
devm_pm_runtime_disable() be called after
devm_mbox_controller_unregister().

CMDQ driver uses devm_mbox_controller_register() in cmdq_probe()\n to bind the cmdq device to the mbox_controller, so\n devm_mbox_controller_unregister() will automatically unregister\n the device bound to the mailbox controller when the device-managed\n resource is removed. That means devm_mbox_controller_unregister()\n and cmdq_mbox_shoutdown() will be called after cmdq_remove().\n2. CMDQ driver also uses devm_pm_runtime_enable() in cmdq_probe() after\n devm_mbox_controller_register(), so that devm_pm_runtime_disable()\n will be called after cmdq_remove(), but before\n devm_mbox_controller_unregister().\n\nTo fix this problem, cmdq_probe() needs to move\ndevm_mbox_controller_register() after devm_pm_runtime_enable() to make\ndevm_pm_runtime_disable() be called after\ndevm_mbox_controller_unregister()."

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
