  "summary": "tun: limit printing rate when illegal packet received by tun dev",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ntun: limit printing rate when illegal packet received by tun dev\n\nvhost_worker will call tun call backs to receive packets. If too many\nillegal packets arrives, tun_do_read will keep dumping packet contents.\nWhen console is enabled, it will costs much more cpu time to dump\npacket and soft lockup will be detected.\n\nnet_ratelimit mechanism can be used to limit the dumping rate.\n\nPID: 33036    TASK: ffff949da6f20000  CPU: 23   COMMAND: \"vhost-32980\"\n #0 [fffffe00003fce50] crash_nmi_callback at ffffffff89249253\n #1 [fffffe00003fce58] nmi_handle at ffffffff89225fa3\n #2 [fffffe00003fceb0] default_do_nmi at ffffffff8922642e\n #3 [fffffe00003fced0] do_nmi at ffffffff8922660d\n #4 [fffffe00003fcef0] end_repeat_nmi at ffffffff89c01663\n    [exception RIP: io_serial_in+20]\n    RIP: ffffffff89792594  RSP: ffffa655314979e8  RFLAGS: 00000002\n    RAX: ffffffff89792500  RBX: ffffffff8af428a0  RCX: 0000000000000000\n    RDX: 00000000000003fd  RSI: 0000000000000005  RDI: ffffffff8af428a0\n    RBP: 0000000000002710   R8: 0000000000000004   R9: 000000000000000f\n    R10: 0000000000000000  R11: ffffffff8acbf64f  R12: 0000000000000020\n    R13: ffffffff8acbf698  R14: 0000000000000058  R15: 0000000000000000\n    ORIG_RAX: ffffffffffffffff  CS: 0010  SS: 0018\n #5 [ffffa655314979e8] io_serial_in at ffffffff89792594\n #6 [ffffa655314979e8] wait_for_xmitr at ffffffff89793470\n #7 [ffffa65531497a08] serial8250_console_putchar at ffffffff897934f6\n #8 [ffffa65531497a20] uart_console_write at ffffffff8978b605\n #9 [ffffa65531497a48] serial8250_console_write at ffffffff89796558\n #10 [ffffa65531497ac8] console_unlock at ffffffff89316124\n #11 [ffffa65531497b10] vprintk_emit at ffffffff89317c07\n #12 [ffffa65531497b68] printk at ffffffff89318306\n #13 [ffffa65531497bc8] print_hex_dump at ffffffff89650765\n #14 [ffffa65531497ca8] tun_do_read at ffffffffc0b06c27 [tun]\n #15 [ffffa65531497d38] tun_recvmsg at ffffffffc0b06e34 [tun]\n #16 [ffffa65531497d68] handle_rx at ffffffffc0c5d682 [vhost_net]\n #17 [ffffa65531497ed0] vhost_worker at ffffffffc0c644dc [vhost]\n #18 [ffffa65531497f10] kthread at ffffffff892d2e72\n #19 [ffffa65531497f50] ret_from_fork at ffffffff89c0022f",
