Descripción técnica

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.

———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.18h CVE-2026-801156.1 MED

———PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain a privilege escalation and denial-of-service vulnerability in DirectIo64.sys that allows local attackers to read arbitrary Model-Specific Registers or write zero to any MSR through exposed IOCTLs with insufficient blocklist enforcement. Attackers can exploit the unrestricted write IOCTL to zero out the system call handler MSR, causing an immediate unrecoverable kernel crash on the next system call, or read security-sensitive MSRs used to locate kernel data structures.18h CVE-2026-801137.1 ALT

———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.18h CVE-2026-387647.8 ALT
