CVE-2026-80113— PassMark PerformanceTest, BurnInTest, and OSForensics Arbitrary Bit Clear via DirectIo64.sys IOCTL

Quick assessment

Affected
PassMark Software PerformanceTest
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

PassMark PerformanceTest 11.1 build 1012 之前的版本、BurnInTest 11.1 build 1000 之前的版本，以及 OSForensics 11.1 build 1016 之前的版本，其 DirectIo64.sys 驱动中存在一个本地权限提升（Privilege Escalation）漏洞。该漏洞是由于暴露的 IOCTL 处理程序未对物理地址参数进行有效校验，允许本地用户清除任意物理内存地址上的特定位。攻击者可以获取设备句柄，并传入一个任意的 64 位物理地址及位

Vulnerability Title
PassMark PerformanceTest, BurnInTest, and OSForensics Arbitrary Bit Clear via DirectIo64.sys IOCTL
Source: CVE Program / CVE List V5
Vulnerability 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 clear arbitrary bits at any physical memory address due to missing validation of the physical address parameter in an exposed IOCTL handler. Attackers can obtain a device handle and supply an arbitrary 64-bit physical address with a bit index to invoke MmMapIoSpace and clear bits in kernel code pages or page table entries, enabling local privilege escalation or system compromise.
