![]() This will happen to all other software using CPUz data, not just ours. I reached out via twitter an this is what corsair support said Seems like the correct way foward is to just not rely on this specific driver. Note that the CPU-Z driver provides numerous other IOCTLs that could be used for exploitation, such as reading from and writing to arbitrary model-specific registers. Without the ability to read the page table base from cr3, the exploitation method in this project is no longer feasible. Furthermore, the IOCTL to read control registers has been removed (although the physical memory read/write implementations remain). Note that when running as an Administrator, it is trivial to enable this privilege from usermode. ![]() If this privilige is missing or disabled, the driver will reject the request with STATUS_ACCESS_DENIED. On requests to open the driver's device object, it will check to see if the current process has the SeLoadDriverPrivilege enabled. From :Īs of version 1.81, the driver provided with CPU-Z has been patched to limit the set of callers that can open its device object and some IOCTL implementations have been removed. Edit: Latest version of CPU-Z also has an outdated driver.
