Summary

In the Linux kernel, the following vulnerability has been resolved: usb: dwc2: fix a devres leak in hw_enable upon suspend resume Each time the platform goes to low power, PM suspend / resume routines call: __dwc2_lowlevel_hw_enable -> devm_add_action_or_reset(). This adds a new devres each time. This may also happen at runtime, as dwc2_lowlevel_hw_enable() can be called from udc_start(). This can be seen with tracing: - echo 1 > /sys/kernel/debug/tracing/events/dev/devres_log/enable - go to low power - cat /sys/kernel/debug/tracing/trace A new "ADD" entry is found upon each low power cycle: ... devres_log: 49000000.usb-otg ADD 82a13bba devm_action_release (8 bytes) ... devres_log: 49000000.usb-otg ADD 49889daf devm_action_release (8 bytes) ... A second issue is addressed here: - regulator_bulk_enable() is called upon each PM cycle (suspend/resume). - regulator_bulk_disable() never gets called. So the reference count for these regulators constantly increase, by one upon each low power cycle, due to missing regulator_bulk_disable() call in __dwc2_lowlevel_hw_disable(). The original fix that introduced the devm_add_action_or_reset() call, fixed an issue during probe, that happens due to other errors in dwc2_driver_probe() -> dwc2_core_reset(). Then the probe fails without disabling regulators, when dr_mode == USB_DR_MODE_PERIPHERAL. Rather fix the error path: disable all the low level hardware in the error path, by using the "hsotg->ll_hw_enabled" flag. Checking dr_mode has been introduced to avoid a dual call to dwc2_lowlevel_hw_disable(). "ll_hw_enabled" should achieve the same (and is used currently in the remove() routine).

Then the probe fails without\ndisabling regulators, when dr_mode == USB_DR_MODE_PERIPHERAL.\n\nRather fix the error path: disable all the low level hardware in the\nerror path, by using the \"hsotg-\u003ell_hw_enabled\" flag. Checking dr_mode\nhas been introduced to avoid a dual call to dwc2_lowlevel_hw_disable().\n\"ll_hw_enabled\" should achieve the same (and is used currently in the\nremove() routine)."

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: dwc2: se corrige una fuga de devres en hw_enable al reanudar la suspensi\u00f3n. Cada vez que la plataforma pasa a bajo consumo, las rutinas de suspensi\u00f3n/reinicio de PM llaman a __dwc2_lowlevel_hw_enable -\u0026gt; devm_add_action_or_reset(). Esto agrega un nuevo devres cada vez. Esto tambi\u00e9n puede ocurrir en tiempo de ejecuci\u00f3n, ya que dwc2_lowlevel_hw_enable() puede llamarse desde udc_start(). Esto se puede ver con el seguimiento: - echo 1 \u0026gt; /sys/kernel/debug/tracing/events/dev/devres_log/enable - ir a bajo consumo - cat /sys/kernel/debug/tracing/trace Se encuentra una nueva entrada \"ADD\" en cada ciclo de bajo consumo: ... devres_log: 49000000.usb-otg ADD 82a13bba devm_action_release (8 bytes) ... devres_log: 49000000.usb-otg ADD 49889daf devm_action_release (8 bytes) ... Aqu\u00ed se aborda un segundo problema: - regulator_bulk_enable() se llama en cada ciclo de PM (suspender/reanudar). - regulator_bulk_disable() nunca se llama. Por lo tanto, el recuento de referencias para estos reguladores aumenta constantemente, en uno con cada ciclo de bajo consumo, debido a la falta de la llamada a regulator_bulk_disable() en __dwc2_lowlevel_hw_disable(). La correcci\u00f3n original, que introdujo la llamada a devm_add_action_or_reset(), solucion\u00f3 un problema durante el sondeo que se produce debido a otros errores en dwc2_driver_probe() -\u0026gt; dwc2_core_reset(). En ese caso, el sondeo falla sin deshabilitar los reguladores cuando dr_mode == USB_DR_MODE_PERIPHERAL. Mejor soluci\u00f3n: deshabilite todo el hardware de bajo nivel en la ruta de error mediante el indicador \"hsotg-\u0026gt;ll_hw_enabled\". Se ha introducido la comprobaci\u00f3n de dr_mode para evitar una llamada dual a dwc2_lowlevel_hw_disable(). \"ll_hw_enabled\" deber\u00eda lograr el mismo efecto (y se utiliza actualmente en la rutina remove())."

Then the probe fails without\ndisabling regulators, when dr_mode == USB_DR_MODE_PERIPHERAL.\n\nRather fix the error path: disable all the low level hardware in the\nerror path, by using the \"hsotg-\u003ell_hw_enabled\" flag. Checking dr_mode\nhas been introduced to avoid a dual call to dwc2_lowlevel_hw_disable().\n\"ll_hw_enabled\" should achieve the same (and is used currently in the\nremove() routine)."

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.
