Haven't found any upstream bugs related to this one by now.

linux-4.10.1/drivers/gpu/drm/nouveau/nvkm/subdev/bios/base.c

nvbios_addr(struct nvkm_bios *bios, u32 *addr, u8 size)
{
    u32 p = *addr;
 
     if (*addr > bios->image0_size && bios->imaged_addr) {
         *addr -= bios->image0_size;
         *addr += bios->imaged_addr;
     }
 
    if (unlikely(*addr + size >= bios->size)) {
         nvkm_error(&bios->subdev, "OOB %d %08x %08x\n", size, p, *addr);
         return false;
     }
 
     return true;
}
