dmesg stacktrace

Hello,
This is my first bug report, I hope I am posting this issue in the correct
place.

I have a userland application which updates dynamically the nft set elements. I
noticed that the filtering (nft) configuration was not changing.

I tried to check the applied rules and set elements using the 'nft list
ruleset' command, but the command hung up and never end.

I noticed through the dmesg command that some kind of kernel error did happend.
I copied the log locally (check attached logfile) and tried to reboot the VM.
The VM never finished rebooting and I had to do a hard reset on the VM.

Some info if it helps troubleshooting the issue:

# uname -a
Linux HOU4716977 6.2.0-37-generic #38-Ubuntu SMP PREEMPT_DYNAMIC Mon Oct 30
21:04:52 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

# nft -v
nftables v1.0.6 (Lester Gooch #5)


Best regards,
Xabier
