CVE-2026-80113Public exploit

Local privilege escalation via unchecked physical addresses

Published Sep 4, 2026 · Updated Sep 10, 2026

Privilege escalation in affected PassMark desktop products allows local users to compromise a Windows system through DirectIo64.sys. IOCTL 0x8011E0A0 passes an unchecked 64-bit physical address to MmMapIoSpace and clears a caller-selected bit in kernel code or page tables. Exploitation requires a device handle and affects PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016; a successful bit clear enables local privilege escalation or a system crash.
