I see the same errors as the OP, although I see somewhat different index
numbers:
UBSAN: array-index-out-of-bounds in
/build/linux-vCyKs5/linux-6.8.0/drivers/media/pci/cx18/cx18-queue.c:345:40
index 64 is out of range for type 'cx18_mdl_ent [1]'
UBSAN: array-index-out-of-bounds in
/build/linux-v
It's a warning for an incorrectly declared flexible array [1]. It
shouldn't cause any issues other than the stack traces. In newer
kernels, a new pedantic gcc flag is used which causes this [2].

Looks like the array is overflow for the definition:
struct cx18_mdl_ent cpu_mdl[1];
It can be simply tested by increased 1 to 1024 or more.
But I am not sure how much buffer the driver want to use,
can we file an upstream bug to notify the driver maintainer?
