CVE-2025-71079

CVE-2025-71079 concerns a Linux kernel deadlock between nfc_unregister_device() and rfkill_fop_write() caused by lock-order inversion (device_lock vs rfkill_global_mutex). The fix moves rfkill_unregister() and rfkill_destroy() outside the device_lock section, storing the rfkill pointer in a local...
