CVE-2026-80116Public exploit

Local privilege escalation via unrestricted PCI IOCTLs

Published Sep 4, 2026 · Updated Sep 8, 2026

Privilege escalation in PassMark PerformanceTest, BurnInTest, and OSForensics allows local users to alter PCI hardware configuration. DirectIo64.sys IOCTLs 0x8011E0A4 and 0x8011E0A8 pass caller-controlled bus, device, function, offset, and value fields to unrestricted PCI configuration-space reads and writes. A caller must obtain the driver device handle; access can enable bus-master DMA, remap BARs, or halt storage-controller I/O, while enforced IOMMU isolation limits DMA-to-RAM impact.
