CVE-2026-80117
PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain a privilege escalation vulner
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.
