Lenovo-CVE-2025-8061

CVE-2025-8061 is a privilege escalation vulnerability in Lenovo's LnvMSRIO.sys driver. The driver exposes IOCTL handlers that allow any user-mode process including unprivileged users to: Read/write arbitrary Model-Specific Registers MSRs Read/write arbitrary physical memory This gives a standard...

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 ...

Stopping Zenbleed CVE-2023-20593 on Windows The newly discovered Zenbleed vulnerability CVE-2023-20593 affects all Zen2 processors from AMD. Unfortunately, AMD will not provide microcode updates for many of its processors until November or December 2023. How to stay safe in the meantime? Luckily,...

kernel: KVM: SVM: Update x2APIC MSR intercepts if AVIC is inhibited while L2 is active

A flaw was found in KVM Kernel-based Virtual Machine. When the Advanced Virtual Interrupt Controller AVIC is inhibited while a nested guest L2 is active, KVM fails to properly update x2APIC MSR intercepts for the primary guest L1. This allows the L1 guest to read the host's APIC state, send...
