Answer in brief
CVE-2026-80118 records a Unknown severity vulnerability in PassMark PerformanceTest, BurnInTest, and OSForensics Kernel Null Pointer Dereference via DirectIo64.sys IOCTL. The current sources do not mark it as known exploited. The current feed maps PassMark Software/BurnInTest (generic), PassMark Software/OSForensics (generic), PassMark Software/PerformanceTest (generic). Check affected ranges and fixed versions before updating.

HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain an unauthenticated physical memory disclosure in DirectIo64.sys, reachable by unprivileged local users through a single IOCTL with no caller-identity check. The handler writes a crash-dump-format (PAGEDU64) image of all physical memory to a caller-supplied file path in the SYSTEM context, allowing a standard user to create files in locations they cannot otherwise write and to recover memory belonging to processes of other users. The image is preceded by a header that exposes the kernel loaded-module list, active-process list and PFN database pointers, defeating KASLR. The same handler also dereferences the return value of an internal kernel-structure locator without a NULL check; that locator returns NULL on three distinct failure paths, and a kernel crash results on builds where any of those paths is taken.
