SUSE CVE-2017-17741

The KVM implementation in the Linux kernel through 4.14.7 allows attackers to obtain potentially sensitive information from kernel memory, aka a writemmio stack-based out-of-bounds read, related to arch/x86/kvm/x86.c and include/trace/events/kvm.h...

SUSE CVE-2018-7540

An issue was discovered in Xen through 4.10.x allowing x86 PV guest OS users to cause a denial of service host OS CPU hang via non-preemptable L3/L4 pagetable freeing...

SUSE CVE-2018-10853

A flaw was found in the way Linux kernel KVM hypervisor before 4.18 emulated instructions such as sgdt/sidt/fxsave/fxrstor. It did not check current privilegeCPL level while emulating unprivileged instructions. An unprivileged guest user/process could use this flaw to potentially escalate...

SUSE CVE-2018-10901

A flaw was found in Linux kernel's KVM virtualization subsystem. The VMX code does not restore the GDT.LIMIT to the previous host value, but instead sets it to 64KB. With a corrupted GDT limit a host's userspace code has an ability to place malicious entries in the GDT, particularly to the per-cp...

SUSE CVE-2018-10981

An issue was discovered in Xen through 4.10.x allowing x86 HVM guest OS users to cause a denial of service host OS infinite loop in situations where a QEMU device model attempts to make invalid transitions between states of a request...

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-2018-16882

A use-after-free issue was found in the way the Linux kernel's KVM hypervisor processed posted interrupts when nested=1 virtualization is enabled. In nestedgetvmcs12pages, in case of an error while processing posted interrupt address, it unmaps the 'pidescpage' without resetting 'pidesc' descript...

SUSE CVE-2018-18883

An issue was discovered in Xen 4.9.x through 4.11.x, on Intel x86 platforms, allowing x86 HVM and PVH guests to cause a host OS denial of service NULL pointer dereference or possibly have unspecified other impact because nested VT-x is not properly restricted...

SUSE CVE-2019-3016

In a Linux KVM guest that has PV TLB enabled, a process in the guest kernel may be able to read memory locations from another process in the same guest. This problem is limit to the host running linux kernel 4.10 with a guest running linux kernel 4.16 or later. The problem mainly affects AMD...

SUSE CVE-2019-3887

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 t...

SUSE CVE-2019-7222

The KVM implementation in the Linux kernel through 4.20.5 has an Information Leak...

SUSE CVE-2019-7221

The KVM implementation in the Linux kernel through 4.20.5 has a Use-after-Free...

SUSE CVE-2019-8934

hw/ppc/spapr.c in QEMU through 3.1.0 allows Information Exposure because the hypervisor shares the /proc/device-tree/system-id and /proc/device-tree/model system attributes with a guest...

SUSE CVE-2019-9836

Secure Encrypted Virtualization SEV on Advanced Micro Devices AMD Platform Security Processor PSP; aka AMD Secure Processor or AMD-SP 0.17 build 11 and earlier has an insecure cryptographic implementation...

SUSE CVE-2019-17340

An issue was discovered in Xen through 4.11.x allowing x86 guest OS users to cause a denial of service or gain privileges because grant-table transfer requests are mishandled...

SUSE CVE-2019-17351

An issue was discovered in drivers/xen/balloon.c in the Linux kernel before 5.2.3, as used in Xen through 4.12.x, allowing guest OS users to cause a denial of service because of unrestricted resource consumption during the mapping of guest memory, aka CID-6ef36ab967c7...

SUSE CVE-2019-18421

An issue was discovered in Xen through 4.12.x allowing x86 PV guest OS users to gain host OS privileges by leveraging race conditions in pagetable promotion and demotion operations. There are issues with restartable PV type change operations. To avoid using shadow pagetables for PV guests, Xen...

SUSE CVE-2019-19332

An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way the Linux kernel's KVM hypervisor handled the 'KVMGETEMULATEDCPUID' ioctl2 request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device...

SUSE CVE-2019-19338

A flaw was found in the fix for CVE-2019-11135, in the Linux upstream kernel versions before 5.5 where, the way Intel CPUs handle speculative execution of instructions when a TSX Asynchronous Abort TAA error occurs. When a guest is running on a host CPU affected by the TAA flaw TAANO=0, but is no...

SUSE CVE-2019-19583

An issue was discovered in Xen through 4.12.x allowing x86 HVM/PVH guest OS users to cause a denial of service guest OS crash because VMX VMEntry checks mishandle a certain case. Please see XSA-260 for background on the MovSS shadow. Please see XSA-156 for background on the need for DB...
