Title

net: nfc: fix deadlock between nfc_unregister_device and rfkill_fop_write

Summary

In the Linux kernel, the following vulnerability has been resolved: net: nfc: fix deadlock between nfc_unregister_device and rfkill_fop_write A deadlock can occur between nfc_unregister_device() and rfkill_fop_write() due to lock ordering inversion between device_lock and rfkill_global_mutex. The problematic lock order is: Thread A (rfkill_fop_write): rfkill_fop_write() mutex_lock(&rfkill_global_mutex) rfkill_set_block() nfc_rfkill_set_block() nfc_dev_down() device_lock(&dev->dev) <- waits for device_lock Thread B (nfc_unregister_device): nfc_unregister_device() device_lock(&dev->dev) rfkill_unregister() mutex_lock(&rfkill_global_mutex) <- waits for rfkill_global_mutex This creates a classic ABBA deadlock scenario. Fix this by moving rfkill_unregister() and rfkill_destroy() outside the device_lock critical section. Store the rfkill pointer in a local variable before releasing the lock, then call rfkill_unregister() after releasing device_lock. This change is safe because rfkill_fop_write() holds rfkill_global_mutex while calling the rfkill callbacks, and rfkill_unregister() also acquires rfkill_global_mutex before cleanup. Therefore, rfkill_unregister() will wait for any ongoing callback to complete before proceeding, and device_del() is only called after rfkill_unregister() returns, preventing any use-after-free. The similar lock ordering in nfc_register_device() (device_lock -> rfkill_global_mutex via rfkill_register) is safe because during registration the device is not yet in rfkill_list, so no concurrent rfkill operations can occur on this device.

Store the rfkill pointer in a local variable\nbefore releasing the lock, then call rfkill_unregister() after releasing\ndevice_lock.\n\nThis change is safe because rfkill_fop_write() holds rfkill_global_mutex\nwhile calling the rfkill callbacks, and rfkill_unregister() also acquires\nrfkill_global_mutex before cleanup. Therefore, rfkill_unregister() will\nwait for any ongoing callback to complete before proceeding, and\ndevice_del() is only called after rfkill_unregister() returns, preventing\nany use-after-free.\n\nThe similar lock ordering in nfc_register_device() (device_lock -\u003e\nrfkill_global_mutex via rfkill_register) is safe because during\nregistration the device is not yet in rfkill_list, so no concurrent\nrfkill operations can occur on this device."

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.
