The destination\nbuffer is data->dev_mem, sized for the nvmem cell's declared 2048\nbytes (ADM1266_BLACKBOX_MAX_RECORDS * ADM1266_BLACKBOX_SIZE = 32 * 64).\nA device that reports a record_count greater than 32 -- whether due\nto firmware bugs, bus corruption, or a non-responsive slave returning\n0xff -- would walk read_buff past the end of the dev_mem allocation\non the trailing iterations.\n\nCap record_count at ADM1266_BLACKBOX_MAX_RECORDS (introduced here)\nbefore entering the loop and return -EIO on any larger value, so a\nmalformed BLACKBOX_INFO response cannot drive the loop out of bounds.",
