CVE-2026-80116

PassMark PerformanceTest, BurnInTest, and OSForensics Privilege Escalation via DirectIo64.sys IOCTL

Published Sep 4, 2026 CVSS 4.0 · 8.5 High EPSS < 1% KEV · Not listed
Description
PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain a privilege escalation vulnerability in DirectIo64.sys that allows local users to modify hardware configuration by exploiting exposed IOCTLs with no validation on device selection, register offset, or value. Attackers can obtain a device handle and issue arbitrary PCI configuration space read/write operations to enable Bus Master DMA on any PCI device, halt storage controller I/O by clearing command registers, or remap Base Address Registers to redirect DMA to an attacker-chosen physical address.
