CVE-2020-15863

A buffer overflow vulnerability was found in the XGMAC Ethernet controller of the QEMU emulator. This flaw occurs during packet transmission and affects the highbank and midway emulated machines. A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a...

CVE-2020-1043

A remote code execution vulnerability exists when Hyper-V RemoteFX vGPU on a host server fails to properly validate input from an authenticated user on a guest operating system, aka 'Hyper-V RemoteFX vGPU Remote Code Execution Vulnerability'. This CVE ID is unique from CVE-2020-1032, CVE-2020-103...

CVE-2020-15469

In QEMU 4.2.0, a MemoryRegionOps object may lack read/write callback methods, leading to a NULL pointer dereference...

Authentication flaw

HUAWEI P30 smartphones with versions earlier than 10.1.0.135C00E135R2P11 have an improper authentication vulnerability. A logic error occurs when handling NFC work, an attacker should establish a NFC connection to the target phone, and then do a series of operations on the target phone. Successfu...

CVE-2020-10717

A potential DoS flaw was found in the virtio-fs shared file system daemon virtiofsd implementation of the QEMU version = v5.0. Virtio-fs is meant to share a host file system directory with a guest via virtio-fs device. If the guest opens the maximum number of file descriptors under the shared...

Directory traversal

A potential DoS flaw was found in the virtio-fs shared file system daemon virtiofsd implementation of the QEMU version = v5.0. Virtio-fs is meant to share a host file system directory with a guest via virtio-fs device. If the guest opens the maximum number of file descriptors under the shared...

CVE-2020-0910

A remote code execution vulnerability exists when Windows Hyper-V on a host server fails to properly validate input from an authenticated user on a guest operating system, aka 'Windows Hyper-V Remote Code Execution Vulnerability'...

UBUNTU-CVE-2020-11742

An issue was discovered in Xen through 4.13.x, allowing guest OS users to cause a denial of service because of bad continuation handling in GNTTABOPcopy. Grant table operations are expected to return 0 for success, and a negative number for errors. The fix for CVE-2017-12135 introduced a path...

Arbitrary Code Execution

qemu is vulnerable to arbitrary code execution. A heap overflow flaw was found in the way QEMU-KVM emulated the e1000 network interface card. A privileged guest user in a virtual machine whose network interface is configured to use the e1000 emulated driver could use this flaw to crash the host o...

Denial Of Service (DoS)

kernel is vulnerable to denial of service. A local guest user is able to crash the application as the cpuid instruction emulation when exiting the VM are not properly handled...

Authorization Bypass

kernel is vulnerable to authorization bypass. In KVM Kernel-based Virtual Machine environments using raw format virtio disks backed by a partition or LVM volume, a privileged guest user could bypass intended restrictions and issue read and write requests and other SCSI commands on the host, and...

Information Disclosure

libguestfs is vulnerable to information disclosure. The vulnerability exists as libguestfs relied on the format auto-detection in QEMU rather than allowing the guest image file format to be specified. A privileged guest user could potentially use this flaw to read arbitrary files on the host that...

Arbitrary Code Execution

qemu-kvm is vulnerable to arbitrary code execution. The vulnerability exists as it was found that the virtio-blk driver in qemu-kvm did not properly validate read and write requests from guests. A privileged guest user could use this flaw to crash the guest or, possibly, execute arbitrary code on...

Privilege Escalation

kvm is vulnerable to privilege escalation. The vulnerability exists as a flaw was found in QEMU-KVM, allowing the guest some control over the index used to access the callback array during sub-page MMIO initialization. A privileged guest user could use this flaw to crash the guest denial of servi...

Privilege Escalation

kvm is vulnerable to privilege escalation. The vulnerability exists as it was found that QEMU-KVM on the host did not validate all pointers provided from a guest system's QXL graphics card driver. A privileged guest user could use this flaw to cause the host to dereference an invalid pointer,...

Denial Of Service (DoS)

The Simple Protocol for Independent Computing Environments SPICE is vulnerable to Denial Of Service DoS. It was found that the libspice component of QEMU-KVM on the host could be forced to perform certain memory management operations on memory addresses controlled by a guest. A privileged guest...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS. The vulnerability exists as a flaw was found in the Xen hypervisor implementation when using the Intel Itanium architecture, allowing guests to enter an unsupported state. An unprivileged guest user could trigger this flaw by setting the BE Big Endia...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS. The vulnerability exists as a flaw was found in the Memory-mapped I/O MMIO instruction decoder in the Xen hypervisor implementation. An unprivileged guest user could use this flaw to trick the hypervisor into emulating a certain instruction, which...
