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-2019-10153

A flaw was discovered in fence-agents, prior to version 4.3.4, where using non-ASCII characters in a guest VM's comment or other fields would cause fencerhevm to exit with an exception. In cluster environments, this could lead to preventing automated recovery or otherwise denying service to...

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-2020-5422

BOSH System Metrics Server releases prior to 0.1.0 exposed the UAA password as a flag to a process running on the BOSH director. It exposed the password to any user or process with access to the same VM through ps or looking at process details...

SUSE CVE-2020-14374

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A flawed bounds checking in the copydata function leads to a buffer overflow allowing an attacker in a virtual machine to write arbitrary data to any address in the vhostcrypto application. The highest threat from this...

SUSE CVE-2020-14375

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. Virtio ring descriptors, and the data they describe are in a region of memory accessible by from both the virtual machine and the host. An attacker in a VM can change the contents of the memory after vhostcrypto has validate...

SUSE CVE-2020-14377

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A complete lack of validation of attacker-controlled parameters can lead to a buffer over read. The results of the over read are then written back to the guest virtual machine memory. This vulnerability can be used by an...

SUSE CVE-2020-15563

An issue was discovered in Xen through 4.13.x, allowing x86 HVM guest OS users to cause a hypervisor crash. An inverted conditional in x86 HVM guests' dirty video RAM tracking code allows such guests to make Xen de-reference a pointer guaranteed to point at unmapped space. A malicious or buggy HV...

SUSE CVE-2020-25651

A flaw was found in the SPICE file transfer protocol. File data from the host system can end up in full or in parts in the client connection of an illegitimate local user in the VM system. Active file transfers from other users could also be interrupted, resulting in a denial of service. The...

SUSE CVE-2020-29480

An issue was discovered in Xen through 4.14.x. Neither xenstore implementation does any permission checks when reporting a xenstore watch event. A guest administrator can watch the root xenstored node, which will cause notifications for every created, modified, and deleted key. A guest...

SUSE CVE-2020-29483

An issue was discovered in Xen through 4.14.x. Xenstored and guests communicate via a shared memory page using a specific protocol. When a guest violates this protocol, xenstored will drop the connection to that guest. Unfortunately, this is done by just removing the guest from xenstored's intern...

SUSE CVE-2021-3308

An issue was discovered in Xen 4.12.3 through 4.12.4 and 4.13.1 through 4.14.x. An x86 HVM guest with PCI pass through devices can force the allocation of all IDT vectors on the system by rebooting itself with MSI or MSI-X capabilities enabled and entries setup. Such reboots will leak any vectors...

SUSE CVE-2021-3546

An out-of-bounds write vulnerability was found in the virtio vhost-user GPU device vhost-user-gpu of QEMU in versions up to and including 6.0. The flaw occurs while processing the 'VIRTIOGPUCMDGETCAPSET' command from the guest. It could allow a privileged guest user to crash the QEMU process on t...

SUSE CVE-2021-3653

A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB virtual machine control block provided by the L1 guest to spawn/handle a nested guest L2. Due to improper validation of the "intctl" field, this issue could allow a malicious ...

SUSE CVE-2021-3656

A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB virtual machine control block provided by the L1 guest to spawn/handle a nested guest L2. Due to improper validation of the "virtext" field, this issue could allow a malicious...

SUSE CVE-2021-4024

A flaw was found in podman. The podman machine function used to create and manage Podman virtual machine containing a Podman process spawns a gvproxy process on the host system. The gvproxy API is accessible on port 7777 on all IP addresses on the host. If that port is open on the host's firewall...

SUSE CVE-2021-4093

A flaw was found in the KVM's AMD code for supporting the Secure Encrypted Virtualization-Encrypted State SEV-ES. A KVM guest using SEV-ES can trigger out-of-bounds reads and writes in the host kernel via a malicious VMGEXIT for a string I/O instruction for example, outs or ins using the exit...

SUSE CVE-2021-25316

A Insecure Temporary File vulnerability in s390-tools of SUSE Linux Enterprise Server 12-SP5, SUSE Linux Enterprise Server 15-SP2 allows local attackers to prevent VM live migrations This issue affects: SUSE Linux Enterprise Server 12-SP5 s390-tools versions prior to 2.1.0-18.29.1. SUSE Linux...

SUSE CVE-2021-26311

In the AMD SEV/SEV-ES feature, memory can be rearranged in the guest address space that is not detected by the attestation mechanism which could be used by a malicious hypervisor to potentially lead to arbitrary code execution within the guest VM if a malicious administrator has access to...

SUSE CVE-2021-26342

In SEV guest VMs, the CPU may fail to flush the Translation Lookaside Buffer TLB following a particular sequence of operations that includes creation of a new virtual machine control block VMCB. The failure to flush the TLB may cause the microcode to use stale TLB translations which may allow for...
