Physical memory disclosure via caller-controlled IOCTL path
Published Sep 4, 2026 · Updated Sep 4, 2026
Information disclosure in affected PassMark PerformanceTest, BurnInTest, and OSForensics builds allows local users to dump physical memory. The DirectIo64.sys 0x8011E084 handler accepts a caller-controlled path, maps every physical page, and writes the image as SYSTEM. A low-privileged local process needs an available device handle; affected releases are PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
