Insufficient input validation on the model specific register: VMHSAVEPA may potentially lead to loss of SEV-SNP guest memory integrity...

SUSE CVE-2014-3601

The kvmiommumappages function in virt/kvm/iommu.c in the Linux kernel through 3.16.1 miscalculates the number of pages during the handling of a mapping failure, which allows guest OS users to 1 cause a denial of service host OS memory corruption or possibly have unspecified other impact by...

A hang vulnerability is possible in the Linux kernel in arch/x86/kvm/mmu/mmu.c. This issue may lead to compromised availability...

kernel: Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks

A flaw was found in the Linux kernel’s KVM implementation, where improper handing of the VMIO|VMPFNMAP VMAs in KVM bypasses RO checks and leads to pages being freed while still accessible by the VMM and guest. This flaw allows users who can start and control a VM to read/write random pages of...
