CVE-2026-80114— PassMark PerformanceTest, BurnInTest, and OSForensics Hard-coded Credentials Authentication Bypass 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 早于 11.1 build 1012 版本、BurnInTest 早于 11.1 build 1000 版本，以及 OSForensics 早于 11.1 build 1016 版本，均存在一个在 驱动中的硬编码凭证漏洞。该漏洞允许本地攻击者通过从分发的二进制文件中提取作为硬编码字面量嵌入的 8 字节密钥，计算任意 IOCTL 写入请求的有效 MD5 认证标签，从而执行任意的物理内存写入操作。 此外，攻击者还可以使用驱动程序自身的“位清除”IOCTL 接口，清除门控

Vulnerability Title
PassMark PerformanceTest, BurnInTest, and OSForensics Hard-coded Credentials Authentication Bypass 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 hard-coded credentials vulnerability in DirectIo64.sys that allows local attackers to perform arbitrary physical memory writes by extracting an 8-byte key embedded as a hardcoded literal in the distributed binary and computing valid MD5 authentication tags for arbitrary IOCTL write requests. Attackers can additionally bypass a secondary validation gate by using the driver's own bit-clear IOCTL to clear a single bit in the gating instruction's displacement byte, causing all subsequent write requests to skip MAC verification, size checks, and Vendor ID checks entirely.
