However, ml_priv is not allocated to the dev,\ndev_rcv_lists is assigned to NULL in can_rx_register(). In this case,\nit will occur the NULL pointer dereference issue.\n\nThe following is the stack information:\nBUG: kernel NULL pointer dereference, address: 0000000000000008\nPGD 122a4067 P4D 122a4067 PUD 1223c067 PMD 0\nOops: 0000 [#1] PREEMPT SMP\nRIP: 0010:can_rx_register+0x12d/0x1e0\nCall Trace:\n<TASK>\nraw_enable_filters+0x8d/0x120\nraw_enable_allfilters+0x3b/0x130\nraw_bind+0x118/0x4f0\n__sys_bind+0x163/0x1a0\n__x64_sys_bind+0x1e/0x30\ndo_syscall_64+0x35/0x80\nentry_SYSCALL_64_after_hwframe+0x63/0xcd\n</TASK>",
