SUSE CVE-2012-0045

The emsyscall function in arch/x86/kvm/emulate.c in the KVM implementation in the Linux kernel before 3.2.14 does not properly handle the 0f05 aka syscall opcode, which allows guest OS users to cause a denial of service guest OS crash via a crafted application, as demonstrated by an NASM file...

SUSE CVE-2015-0239

The emsysenter function in arch/x86/kvm/emulate.c in the Linux kernel before 3.18.5, when the guest OS lacks SYSENTER MSR initialization, allows guest OS users to gain guest OS privileges or cause a denial of service guest OS crash by triggering use of a 16-bit code segment for emulation of a...

SUSE CVE-2017-7518

A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flagTF bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exceptionDB being raised in the guest stack. A user/process inside a guest could use this flaw to...

GSD-2022-1006321 KVM: x86: Mark TSS busy during LTR emulation _after_ all fault checks

KVM: x86: Mark TSS busy during LTR emulation after all fault checks This is an automated ID intended to aid in discovery of potential security vulnerabilities. The actual impact and attack plausibility have not yet been proven. This ID is fixed in Linux Kernel version v4.9.326 by commit...

kernel: kvm: reporting emulation failures to userspace

It was found that reporting emulation failures to user space could lead to either a local CVE-2014-7842 or a L2-L1 CVE-2010-5313 denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to access an I/O port. Please note that on certain...
