CVE-2026-80117— PassMark PerformanceTest, BurnInTest, and OSForensics Arbitrary I/O Port Access via DirectIo64.sys

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 版本（build 1012）之前、BurnInTest 11.1 版本（build 1000）之前，以及 OSForensics 11.1 版本（build 1016）之前，其 驱动程序存在权限提升漏洞。由于暴露的 IOCTL 接口缺少端口允许列表或端口验证机制，本地用户可以向任意 x86 I/O 端口发出任意的 IN 和 OUT 指令。攻击者可以从标准用户账户获取设备句柄，并向敏感端口写入数据，包括 PS/2 控制器端口、CPU 重置端口、CMOS 配置

Vulnerability Title
PassMark PerformanceTest, BurnInTest, and OSForensics Arbitrary I/O Port Access via DirectIo64.sys
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 issue arbitrary IN and OUT instructions to any x86 I/O port due to missing allowlist or port validation on exposed IOCTLs. Attackers can obtain a device handle and write to sensitive ports including the PS/2 controller port, CPU reset ports, CMOS configuration ports, and interrupt controller ports to cause an immediate system reset or other hardware-level manipulation from a standard user account.
