The error message you're encountering appears to be related to a known issue reported in Ubuntu's bug tracker. The bug report [Bug #2058480](https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2058480) describes a similar problem where newly launched Ubuntu 22.04.4 EC2 instances output "UBSAN: array-index-out-of-bounds in /build/linux-aws-6.5-4tw9h1/linux-aws-6.5-6.5.0/drivers/net/xen-netfront.c:349:9" multiple times, particularly during boot.
Keep your system updated and monitor the bug report, you should be able to mitigate or resolve the problem.
