  "title": "net: nfc: fix deadlock between nfc_unregister_device and rfkill_fop_write",
  "description": "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(\u0026rfkill_global_mutex)       rfkill_set_block()         nfc_rfkill_set_block()           nfc_dev_down()             device_lock(\u0026dev-\u003Edev)    \u003C- waits for device_lock  Thread B (nfc_unregister_device):   nfc_unregister_device()     device_lock(\u0026dev-\u003Edev)       rfkill_unregister()         mutex_lock(\u0026rfkill_global_mutex)  \u003C- 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 -\u003E 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.",
