SUSE CVE-2019-17351

An issue was discovered in drivers/xen/balloon.c in the Linux kernel before 5.2.3, as used in Xen through 4.12.x, allowing guest OS users to cause a denial of service because of unrestricted resource consumption during the mapping of guest memory, aka CID-6ef36ab967c7...

SUSE CVE-2019-18421

An issue was discovered in Xen through 4.12.x allowing x86 PV guest OS users to gain host OS privileges by leveraging race conditions in pagetable promotion and demotion operations. There are issues with restartable PV type change operations. To avoid using shadow pagetables for PV guests, Xen...

SUSE CVE-2019-19332

An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way the Linux kernel's KVM hypervisor handled the 'KVMGETEMULATEDCPUID' ioctl2 request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device...

SUSE CVE-2019-19338

A flaw was found in the fix for CVE-2019-11135, in the Linux upstream kernel versions before 5.5 where, the way Intel CPUs handle speculative execution of instructions when a TSX Asynchronous Abort TAA error occurs. When a guest is running on a host CPU affected by the TAA flaw TAANO=0, but is no...

Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization component: Core. Supported versions that are affected are Prior to 5.2.36, prior to 6.0.16 and prior to 6.1.2. Difficult to exploit vulnerability allows high privileged attacker with logon to the infrastructure where Oracl...

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-2020-25598

An issue was discovered in Xen 4.14.x. There is a missing unlock in the XENMEMacquireresource error path. The RCU Read, Copy, Update mechanism is a synchronisation primitive. A buggy error path in the XENMEMacquireresource exits without releasing an RCU reference, which is conceptually similar to...

SUSE CVE-2020-25604

An issue was discovered in Xen through 4.14.x. There is a race condition when migrating timers between x86 HVM vCPUs. When migrating timers of x86 HVM guests between its vCPUs, the locking model used allows for a second vCPU of the same guest also operating on the timers to release a lock that it...

SUSE CVE-2020-27673

An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. Guest OS users can cause a denial of service host OS hang via a high rate of events to dom0, aka CID-e99502f76271...

SUSE CVE-2020-27675

An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. drivers/xen/events/eventsbase.c allows event-channel removal during the event-handling loop a race condition. This can cause a use-after-free or NULL pointer dereference, as demonstrated by a dom0 crash vi...

SUSE CVE-2020-27777

A flaw was found in the way RTAS handled memory accesses in userspace to kernel communication. On a locked down usually due to Secure Boot guest system running on top of PowerVM or KVM hypervisors pseries platform a root like local user could use this flaw to further increase their privileges to...

SUSE CVE-2020-29567

An issue was discovered in Xen 4.14.x. When moving IRQs between CPUs to distribute the load of IRQ handling, IRQ vectors are dynamically allocated and de-allocated on the relevant CPUs. De-allocation has to happen when certain constraints are met. If these conditions are not met when first checke...

SUSE CVE-2020-36310
