LolModapi

嗨，黑客们。 这是一个 MODAPI.sys 中的未认证 MSR 写入漏洞，该内核驱动由 MSI Dragon Center 2.0.155.0 安装。该驱动暴露了一个设备对象，其安全描述符允许任何本地用户打开它，无需管理员权限，也无需 UAC。一旦获得句柄，MSR 索引上就没有白名单限制，因此你可以随意读写任何 MSR。 读取侧本身就已经能破坏 KASLR。读取 IA32LSTAR 0xC0000082，驱动就会免费把 ntoskrnl!KiSystemCall64 交给你。写入侧才是真正的问题所在。IA32LSTAR 是 CPU 在 syscall...

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-2026-23005

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...

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....
