kernel: KVM: x86/mmu: race condition in direct_page_fault()

A flaw was found in the Linux kernel in the KVM. A race condition in directpagefault allows guest OS users to cause a denial of service host OS crash or host OS memory corruption when nested virtualization and the TDP MMU are enabled...

Information Disclosure

github.com/moby/hyperkit is vulnerable to Information Disclosure. The vulnerability exists in the pcivtblkproc function of pcivirtioblock.c, which leads to the disclosure of host memory into the virtualized guest...

Design/Logic Flaw

HyperKit is a toolkit for embedding hypervisor capabilities in an application. In versions 0.20210107 and prior, a malicious guest can trigger a vulnerability in the host by abusing the disk driver that may lead to the disclosure of the host memory into the virtualized guest. This issue is fixed ...

CVE-2021-32847

HyperKit versions 0.20210107 and earlier are affected by a vulnerability in the disk driver that can cause host memory disclosure to a malicious guest. The issue is described as a memory-related flaw (uninitialized memory use) in the PCI virtio block path (pci_vtsock_proc_tx) and is associated wi...

The VGA emulator in QEMU allows local guest users to read host memory by setting the display to a high resolution...

SUSE CVE-2014-8369

The kvmiommumappages function in virt/kvm/iommu.c in the Linux kernel through 3.17.2 miscalculates the number of pages during the handling of a mapping failure, which allows guest OS users to cause a denial of service host OS page unpinning or possibly have unspecified other impact by leveraging...

SUSE CVE-2015-5261

Heap-based buffer overflow in SPICE before 0.12.6 allows guest OS users to read and write to arbitrary memory locations on the host via guest QXL commands related to surface creation...

SUSE CVE-2015-8553

Xen allows guest OS users to obtain sensitive information from uninitialized locations in host OS kernel memory by not enabling memory and I/O decoding control bits. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-0777...

SUSE CVE-2015-8568

Memory leak in QEMU, when built with a VMWARE VMXNET3 paravirtual NIC emulator support, allows local guest users to cause a denial of service host memory consumption by trying to activate the vmxnet3 device repeatedly...

SUSE CVE-2016-2150

SPICE allows local guest OS users to read from or write to arbitrary host memory locations via crafted primary surface parameters, a similar issue to CVE-2015-5261...

SUSE CVE-2016-5105

The megasasdcmdcfgread function in hw/scsi/megasas.c in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, uses an uninitialized variable, which allows local guest administrators to read host memory via vectors involving a MegaRAID Firmware Interface MFI command...

SUSE CVE-2016-6836

The vmxnet3completepacket function in hw/net/vmxnet3.c in QEMU aka Quick Emulator allows local guest OS administrators to obtain sensitive host memory information by leveraging failure to initialize the txcqdescr object...

SUSE CVE-2016-9845

QEMU aka Quick Emulator built with the Virtio GPU Device emulator support is vulnerable to an information leakage issue. It could occur while processing 'VIRTIOGPUCMDGETCAPSETINFO' command. A guest user/process could use this flaw to leak contents of the host memory bytes...

SUSE CVE-2016-9846

QEMU aka Quick Emulator built with the Virtio GPU Device emulator support is vulnerable to a memory leakage issue. It could occur while updating the cursor data in updatecursordatavirgl. A guest user/process could use this flaw to leak host memory bytes, resulting in DoS for a host...
