I've upgraded ubuntu 23.04 to 23.10 and I've got the bug that you said that should have been fixed.
On my Ubuntu 23.10 I'm using kernel 6.5.0-10-generic and I've installed the nvidia driver version 535.129.03. (my nvidia gpu is the RTX 2080 ti ; my cpu is the intel I9) Not exactly the same bug because the error in the Ubuntu bug report is for a different kernel module. But the underlying cause is probably the same. Ubuntu is probably at fault here. Possibly the code for the nvidia-uvm module is designed for kernel versions < 6.5, so when Ubuntu upgraded to Linux kernel 6.5, it broke some modules because of changes to UBSAN in Linux 6.5 which causes modules such as nvidia-uvm to need patches to be compatible with Linux 6.5, but either nvidia has not yet provided a version of nvidia-uvm that is compatible with Linux 6.5 or Ubuntu neglected to apply an updated version from nvidia that is compatible with Linux 6.5. Whois the guilty ? the nvidia or the ubuntu developers ? I didn't see this error on ubuntu 23.04,maybe because it does not use the kernel 6.5 by default,but 23.10 does it. I see a lot of those errors when I issue the command "dmesg" and any audio-video streamings don't flow.
