CVE-2026-75809—1.3%
——0Exposed IOCTL with insufficient access control in ASUS Armoury Crate allows a local user to disclosure information and disabling device functionality by bypassing driver authentication and using IOCTLs to read from and write to PCIe configuration space.Refer to the '
Security Update for Armoury Crate App ' section on the ASUS Security Advisory for more information.8dCVE-2026-16004—0.5%
——0Exposed IOCTL with Insufficient Access Control in Armoury Crate driver allows a local user to read and write arbitrary PCI/PCIe configuration space via crafted IOCTL requests by bypassing the driver's verification.

Security Update for Armoury Crate App' section on the ASUS Security Advisory for more information.8dCVE-2026-16003—0.5%
——0Exposed IOCTL with Insufficient Access Control in Armoury Crate driver allows a local user to add an arbitrary process identifier to the driver's whitelist via a crafted IOCTL request by bypassing the driver's verification.Refer to the '

——0PassMark 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.8dCVE-2026-801167.8 HIG1.7%
——1PassMark 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.8dCVE-2026-801156.1 MED1.3%
——0PassMark 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.2d
