kernel: KVM: NULL pointer dereference in kvm_mmu_invpcid_gva
A flaw was found in KVM. With shadow paging enabled if INVPCID is executed with CR0.PG=0, the invlpg callback is not set, and the result is a NULL pointer dereference. This flaw allows a guest user to cause a kernel oops condition on the host, resulting in a denial of service...

SUSE CVE-2009-1242
The vmxsetmsr function in arch/x86/kvm/vmx.c in the VMX implementation in the KVM subsystem in the Linux kernel before 2.6.29.1 on the i386 platform allows guest OS users to cause a denial of service OOPS by setting the EFERLME aka "Long mode enable" bit in the Extended Feature Enable Register EF...
SUSE CVE-2009-3290
The kvmemulatehypercall function in arch/x86/kvm/x86.c in KVM in the Linux kernel 2.6.25-rc1, and other versions before 2.6.31, when running on x86 systems, does not prevent access to MMU hypercalls from ring 0, which allows local guest OS users to cause a denial of service guest kernel crash and...
SUSE CVE-2010-0435
The Hypervisor aka rhev-hypervisor in Red Hat Enterprise Virtualization RHEV 2.2, and KVM 83, when the Intel VT-x extension is enabled, allows guest OS users to cause a denial of service NULL pointer dereference and host OS crash via vectors related to instruction emulation...
SUSE CVE-2011-4622
The createpittimer function in arch/x86/kvm/i8254.c in KVM 83, and possibly other versions, does not properly handle when Programmable Interval Timer PIT interrupt requests IRQs when a virtual interrupt controller irqchip is not available, which allows local users to cause a denial of service NUL...
SUSE CVE-2013-6368
The KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges or cause a denial of service system crash via a VAPIC synchronization operation involving a page-end address...
SUSE CVE-2014-3611
Race condition in the kvmmigratepittimer function in arch/x86/kvm/i8254.c in the KVM subsystem in the Linux kernel through 3.17.2 allows guest OS users to cause a denial of service host OS crash by leveraging incorrect PIT emulation...
SUSE CVE-2014-3647
arch/x86/kvm/emulate.c in the KVM subsystem in the Linux kernel through 3.17.2 does not properly perform RIP changes, which allows guest OS users to cause a denial of service guest OS crash via a crafted application...
SUSE CVE-2020-2732
A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into accessing sensitive L1 resources that should be inaccessible to the L2 guest...
SUSE CVE-2021-37576
arch/powerpc/kvm/book3srtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest OS users to cause host OS memory corruption via rtasargs.nargs, aka CID-f62f3c20647e...
SUSE CVE-2022-1158
A flaw was found in KVM. When updating a guest's page table entry, vmpgoff was improperly used as the offset to get the page's pfn. As vaddr and vmpgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and...
SUSE CVE-2022-1263
A NULL pointer dereference issue was found in KVM when releasing a vCPU with dirty ring support enabled. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service...
SUSE CVE-2022-45869
