What is CVE-2026-80116?
CVE-2026-80116 is a high-severity vulnerability in PassMark Software BurnInTest, published on 4 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
Weakness: CWE-782
