Based on this comment, the vulnerability is non-existent in cpuz_145圆4.sys and above. The vulnerability has, however, been patched since 2017. NOTE: the vendor indicates that the arbitrary read itself is intentional behavior (for ACPI scan functionality) the security issue is the lack of an ACL.Īnd based on this, it's understandable that Vanguard nopes hard on it. Furthermore, the driver can map any physical page on the system and returns the allocated map page address to the user: that results in an information leak and EoP. Any application running on the system (Windows), including sandboxed users, can issue an ioctl to this driver without any validation. In CPUID CPU-Z through 1.81, there are improper access rights to a kernel-mode driver (e.g., cpuz143_圆4.sys for version 1.43) that can result in information disclosure or elevation of privileges, because of an arbitrary read of any physical address via ioctl 0x9C402604. The CPU-Z driver had a vulnerability up to, and including, version 1.81, which was abused by hackers - both the cheating and the bank-account-stealing kinds.ĬVEDetails report followign on the vulnerability: MSI Afterburner, NZXT CAM and programs like them are often using it. They are the makers of CPU-Z, the drivers of which are utilized in many other proprietary programs.
If you don't know CPUID, you've probably still used their software, in one form or another.
