AMD Processors 安全漏洞

AMD Processors is a processor from Ultraviolet Semiconductor AMD. A security vulnerability exists in AMD Processors that stems from incorrect validation in model-specific registers and could allow a malicious program with access privileges to modify the SMM configuration with SMI locking enabled,...

SUSE CVE-2021-46977

In the Linux kernel, the following vulnerability has been resolved: KVM: VMX: Disable preemption when probing user return MSRs Disable preemption when probing a user return MSR via RDSMR/WRMSR. If the MSR holds a different value per logical CPU, the WRMSR could corrupt the host's value if KVM is...

Kernel: kvm: svm: improper check in svm_set_x2apic_msr_interception allows direct access to host x2apic msrs

kernel: save/restore speculative MSRs during S3 suspend/resume

A flaw was found in the Linux kernel X86 CPU Power management when resuming CPU from suspend-to-RAM. This issue could allow a local user unauthorized access to memory from the CPU...

CVE-2022-42455

ASUS EC Tool driver aka d.sys 1beb15c90dcf7a5234ed077833a0a3e900969b60be1d04fcebce0a9f8994bdbb, as signed by ASUS and shipped with multiple ASUS software products, contains multiple IOCTL handlers that provide raw read and write access to port I/O and MSRs via unprivileged IOCTL calls. Local user...

SUSE CVE-2015-8844

The signal implementation in the Linux kernel before 4.3.5 on powerpc platforms does not check for an MSR with both the S and T bits set, which allows local users to cause a denial of service TM Bad Thing exception and panic via a crafted application...

kernel: KVM: NULL pointer dereference in kvm_irq_delivery_to_apic_fast()

A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a...

CVE-2021-28685

AsIO264.sys and AsIO232.sys in ASUS GPUTweak II before 2.3.0.3 allow low-privileged users to interact directly with physical memory by calling one of several driver routines that map physical memory into the virtual address space of the calling process and to interact with MSR registers. This cou...

CVE-2020-28921

An issue was discovered in Devid Espenschied PC Analyser through 4.10. The PCADRVX64.SYS kernel driver exposes IOCTL functionality that allows low-privilege users to read and write to arbitrary Model Specific Registers MSRs. This could lead to arbitrary Ring-0 code execution and escalation of...

An issue was discovered in Devid Espenschied PC Analyser through 4.10. The PCADRVX64.SYS kernel driver exposes IOCTL functionality that allows low-privilege users to read and write to arbitrary Model Specific Registers MSRs. This could lead to arbitrary Ring-0 code execution and escalation of...

Devid Espenschied PC Analyser License Issue Vulnerability

Devid Espenschied Devid Espenschied PC Analyser is a software for diagnostics, stress testing, and configuration comparison of PC systems from Devid Espenschied, Germany. A security vulnerability exists in Devid Espenschied PC Analyser version 4.10 and earlier versions, which stems from the...

ALPINE-CVE-2020-25602

An issue was discovered in Xen through 4.14.x. An x86 PV guest can trigger a host OS crash when handling guest access to MSRMISCENABLE. When a guest accesses certain Model Specific Registers, Xen first reads the value from hardware to use as the basis for auditing the guest access. For the...

CVE-2020-25602

A flaw was found in Xen, specifically when a guest accesses certain Model Specific Registers where Xen first reads the value from hardware to use as the basis for auditing the guest access. For the MISCENABLE MSR, an Intel specific MSR, this MSR read is performed without error handling for a GP...

x86 pv: Crash when handling guest access to MSR_MISC_ENABLE

ISSUE DESCRIPTION When a guest accesses certain Model Specific Registers, Xen first reads the value from hardware to use as the basis for auditing the guest access. For the MISCENABLE MSR, which is an Intel specific MSR, this MSR read is performed without error handling for a GP fault, which is t...
