LolModapi

hi hackers. This one is an unauthenticated MSR write inside MODAPI.sys, the kernel driver that MSI Dragon Center 2.0.155.0 installs. The driver exposes a device object with a security descriptor that lets any local user open it, no admin and no UAC. Once you have the handle there is no whitelist ...

CVE-2026-80115

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 the DirectIo64.sys kernel driver. The root cause is exposed IOCTLs with insufficient blocklist enf...

CVE-2026-80115 PassMark PerformanceTest, BurnInTest, and OSForensics Kernel Crash via DirectIo64.sys MSR Write IOCTL

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 a...

CVE-2026-80115 PassMark PerformanceTest, BurnInTest, and OSForensics Kernel Crash via DirectIo64.sys MSR Write IOCTL

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 a...

CVE-2026-23005

In the Linux kernel, the following vulnerability has been resolved: x86/fpu: Clear XSTATEBVi in guest XSAVE state whenever XFDi=1 When loading guest XSAVE state via KVMSETXSAVE, and when updating XFD in response to a guest WRMSR, clear XFD-disabled features in the saved or to be restored XSTATEBV...

CVE-2019-7240

An issue was discovered in WinRing0x64.sys in Moo0 System Monitor 1.83. The vulnerable driver exposes a wrmsr instruction via IOCTL 0x9C402088 and does not properly filter the Model Specific Register MSR. Allowing arbitrary MSR writes can lead to Ring-0 code execution and escalation of privileges...

CVE-2019-7245: Improper Initialization

An issue was discovered in GPU-Z.sys in TechPowerUp GPU-Z before 2.23.0. The vulnerable driver exposes a wrmsr instruction via an IOCTL and does not properly filter the Model Specific Register MSR. Allowing arbitrary MSR writes can lead to Ring-0 code execution and escalation of privileges...

netOctopus Agent nantsys.sys MSR Write Local Privilege Escalation

netOctopus Agent, an asset management agent, is installed on the remote host. The installed version of netOctopus Agent includes a driver, named 'nantsys.sys', that exposes a device interface writable by all local users, allowing them to read and write arbitrary CPU Model Specific Registers MSRs....
