SUSE CVE-2016-3713

The msrmtrrvalid function in arch/x86/kvm/mtrr.c in the Linux kernel before 4.6.1 supports MSR 0x2f8, which allows guest OS users to read or write to the kvmarchvcpu data structure, and consequently obtain sensitive information or cause a denial of service system crash, via a crafted ioctl call...

AMD μProf 安全漏洞

AMD μProf is a performance analysis tool from AMD for applications running on Windows, Linux and FreeBSD operating systems. A security vulnerability exists in AMD μProf, which stems from the fact that the AMDPowerProfiler.sys driver may allow a low-privileged user to access the MSR in the kernel,...

A flaw was found in the way KVM hypervisor handled x2APIC Machine Specific Rregister (MSR) access with nested(=1) virtualization enabled. In that L1 guest could access L0's APIC register values via L2 guest when 'virtualize x2APIC mode' is enabled. A guest could use this flaw to potentially crash the host kernel resulting in DoS issue. Kernel versions from 4.16 and newer are vulnerable to this issue.
