CVE-2024-27013

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. PID: 33036 TASK: ffff949da6f20000 CPU: 23 COMMAND: “vhost-32980” #0
