Its callback\nfrees the skb data in pn533_send_async_complete() that is used as a\ntransfer buffer of out_urb. Wait before sending in_urb until the\ncallback of out_urb is called. To modify the callback of out_urb alone,\nseparate the complete function of out_urb and ack_urb.\n\nFound by a modified version of syzkaller.\n\nBUG: KASAN: use-after-free in dummy_timer\nCall Trace:\n memcpy (mm/kasan/shadow.c:65)\n dummy_perform_transfer (drivers/usb/gadget/udc/dummy_hcd.c:1352)\n transfer (drivers/usb/gadget/udc/dummy_hcd.c:1453)\n dummy_timer (drivers/usb/gadget/udc/dummy_hcd.c:1972)\n arch_static_branch (arch/x86/include/asm/jump_label.h:27)\n static_key_false (include/linux/jump_label.h:207)\n timer_expire_exit (include/trace/events/timer.h:127)\n call_timer_fn (kernel/time/timer.c:1475)\n expire_timers (kernel/time/timer.c:1519)\n __run_timers (kernel/time/timer.c:1790)\n run_timer_softirq (kernel/time/timer.c:1803)",
