[Bug 2073367] Re: bug in module cx18

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-vCyKs5/linux-6.8.0/drivers/media/pci/cx18/cx18-queue.c:293:26
index 136 is out of range for type 'cx18_mdl_ent [1]'
UBSAN: array-index-out-of-bounds in /build/linux-vCyKs5/linux-6.8.0/drivers/media/pci/cx18/cx18-queue.c:295:26
index 136 is out of range for type 'cx18_mdl_ent [1]'
UBSAN: array-index-out-of-bounds in /build/linux-vCyKs5/linux-6.8.0/drivers/media/pci/cx18/cx18-streams.c:705:39
index 136 is out of range for type 'cx18_mdl_ent [1]'

I am not currently trying to use the card, but I could hook up an antenna, if there's a patch to test.
This is on older hardware than the OP's, with an AMD Athlon(tm) Dual Core Processor 4850e. LMK if you'd like more info.
