CVE-2026-80118Public exploit

Local physical memory disclosure via unchecked IOCTL

Published Sep 4, 2026 · Updated Sep 10, 2026

Physical memory disclosure in affected PerformanceTest, BurnInTest, and OSForensics builds allows local users to dump RAM via an IOCTL. DirectIo64.sys IOCTL 0x8011E080 accepts a caller-supplied path, writes a PAGEDU64 image as SYSTEM without checking caller identity, and dereferences an unchecked kernel-structure locator result. Affected releases are PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016; an unprivileged user needs access to the driver device.
