CIS. Coverity has tagged it as tainted. While this data is more trusted than your average data, we still need to do some basic validation on it. Check ioctl return value to ensure we switch memory targets between common and attribute as well as the lseek. CID: 1210464, 1006640, 1006868, 1007292, 1009091, 1009822, 1009824
