The eepro100 emulator in QEMU qemu-kvm blank allows local guest users to cause a denial of service application crash and infinite loop via vectors involving the command block list...
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...
SUSE CVE-2016-4440
arch/x86/kvm/vmx.c in the Linux kernel through 4.6.3 mishandles the APICv on/off state, which allows guest OS users to obtain direct APIC MSR access on the host OS, and consequently cause a denial of service host OS crash or possibly execute arbitrary code on the host OS, via x2APIC mode...
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...
SUSE CVE-2017-8106
The handleinvept function in arch/x86/kvm/vmx.c in the Linux kernel 3.12 through 3.15 allows privileged KVM guest OS users to cause a denial of service NULL pointer dereference and host OS crash via a single-context INVEPT instruction with a NULL EPT pointer...
SUSE CVE-2018-12473
A path traversal traversal vulnerability in obs-service-tarscm of Open Build Service allows remote attackers to cause access files not in the current build. On the server itself this is prevented by confining the worker via KVM. Affected releases are openSUSE Open Build Service: versions prior to...
SUSE CVE-2018-12904
In arch/x86/kvm/vmx.c in the Linux kernel before 4.17.2, when nested virtualization is used, local attackers could cause L1 KVM guests to VMEXIT, potentially allowing privilege escalations and denial of service attacks due to lack of checking of CPL...
SUSE CVE-2019-14821
An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvmcoalescedmmio' object, wherein write indices 'ring-first' and 'ring-last'...
SUSE CVE-2020-36312
