漏洞描述
In the Linux kernel, the following vulnerability has been resolved:

tun: limit printing rate when illegal packet received by tun dev

vhost_worker will call tun call backs to receive packets. If too many
illegal packets arrives, tun_do_read will keep dumping packet contents.
When console is enabled, it will costs much more cpu time to dump
packet and soft lockup will be detected.

net_ratelimit mechanism can be used to limit the dumping rate.
