A vulnerability in the DirectIo64.sys component affects multiple PassMark products including BurnInTest v11.0 Build 1011, OSForensics v11.1 Build 1007, and PerformanceTest v11.1 Build 1004. The vulnerability allows attackers to access kernel memory and escalate privileges through a crafted IOCTL 0x8011E044 call. This is a kernel-level vulnerability that could provide attackers with elevated system access. The affected component is a driver that appears to be shared across multiple PassMark software products. The specific IOCTL code 0x8011E044 indicates a precise attack vector for exploitation.
