| CVE-2015-2044 | 1 Xen | 1 Xen | 2018-10-30 | 2.1 LOW | N/A |
| The emulation routines for unspecified X86 devices in Xen 3.2.x through 4.5.x does not properly initialize data, which allow local HVM guest users to obtain sensitive information via vectors involving an unsupported access size. | |||||
| CVE-2015-7972 | 1 Xen | 1 Xen | 2018-10-30 | 2.1 LOW | N/A |
| The (1) libxl_set_memory_target function in tools/libxl/libxl.c and (2) libxl__build_post function in tools/libxl/libxl_dom.c in Xen 3.4.x through 4.6.x do not properly calculate the balloon size when using the populate-on-demand (PoD) system, which allows local HVM guest users to cause a denial of service (guest crash) via unspecified vectors related to "heavy memory pressure." | |||||
| CVE-2015-3259 | 1 Xen | 1 Xen | 2018-10-30 | 6.8 MEDIUM | N/A |

| The vgic_v2_to_sgi function in arch/arm/vgic-v2.c in Xen 4.5.x, when running on ARM hardware with general interrupt controller (GIC) version 2, allows local guest users to cause a denial of service (host crash) by writing an invalid value to the GICD.SGIR register. | |||||
| CVE-2014-7156 | 1 Xen | 1 Xen | 2018-10-30 | 3.3 LOW | N/A |
| The x86_emulate function in arch/x86/x86_emulate/x86_emulate.c in Xen 3.3.x through 4.4.x does not check the supervisor mode permissions for instructions that generate software interrupts, which allows local HVM guest users to cause a denial of service (guest crash) via unspecified vectors. | |||||
| CVE-2014-4021 | 1 Xen | 1 Xen | 2018-10-30 | 2.7 LOW | N/A |
| Xen 3.2.x through 4.4.x does not properly clean memory pages recovered from guests, which allows local guest OS users to obtain sensitive information via unspecified vectors. | |||||
| CVE-2014-3714 | 1 Xen | 1 Xen | 2018-10-30 | 3.3 LOW | N/A |
| The ARM image loading functionality in Xen 4.4.x does not properly validate kernel length, which allows local users to read system memory or cause a denial of service (crash) via a crafted 32-bit ARM guest kernel in an image, which triggers a buffer overflow. | |||||
| CVE-2014-7188 | 1 Xen | 1 Xen | 2018-10-30 | 8.3 HIGH | N/A |
| The hvm_msr_read_intercept function in arch/x86/hvm/hvm.c in Xen 4.1 through 4.4.x uses an improper MSR range for x2APIC emulation, which allows local HVM guests to cause a denial of service (host crash) or read data from the hypervisor or other guests via unspecified vectors. | |||||
| CVE-2015-7969 | 1 Xen | 1 Xen | 2018-10-30 | 4.9 MEDIUM | N/A |
| Multiple memory leaks in Xen 4.0 through 4.6.x allow local guest administrators or domains with certain permission to cause a denial of service (memory consumption) via a large number of "teardowns" of domains with the vcpu pointer array allocated using the (1) XEN_DOMCTL_max_vcpus hypercall or the xenoprofile state vcpu pointer array allocated using the (2) XENOPROF_get_buffer or (3) XENOPROF_set_passive hypercall. | |||||
| CVE-2017-15595 | 1 Xen | 1 Xen | 2018-10-30 | 7.2 HIGH | 8.8 HIGH |
| An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to cause a denial of service (unbounded recursion, stack consumption, and hypervisor crash) or possibly gain privileges via crafted page-table stacking. | |||||
| CVE-2017-15588 | 1 Xen | 1 Xen | 2018-10-19 | 6.9 MEDIUM | 7.8 HIGH |
| An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to execute arbitrary code on the host OS because of a race condition that can cause a stale TLB entry. | |||||
| CVE-2017-14316 | 1 Xen | 1 Xen | 2018-10-19 | 7.2 HIGH | 8.8 HIGH |
| A parameter verification issue was discovered in Xen through 4.9.x. The function `alloc_heap_pages` allows callers to specify the first NUMA node that should be used for allocations through the `memflags` parameter; the node is extracted using the `MEMF_get_node` macro. While the function checks to see if the special constant `NUMA_NO_NODE` is specified, it otherwise does not handle the case where `node >= MAX_NUMNODES`. This allows an out-of-bounds access to an internal array. | |||||
| CVE-2017-17564 | 1 Xen | 1 Xen | 2018-10-19 | 6.9 MEDIUM | 7.8 HIGH |
| An issue was discovered in Xen through 4.9.x allowing guest OS users to cause a denial of service (host OS crash) or gain host OS privileges by leveraging incorrect error handling for reference counting in shadow mode. | |||||
| CVE-2017-17565 | 1 Xen | 1 Xen | 2018-10-19 | 4.7 MEDIUM | 5.6 MEDIUM |
| An issue was discovered in Xen through 4.9.x allowing PV guest OS users to cause a denial of service (host OS crash) if shadow mode and log-dirty mode are in place, because of an incorrect assertion related to M2P. | |||||
| CVE-2017-14317 | 1 Xen | 1 Xen | 2018-10-19 | 4.7 MEDIUM | 5.6 MEDIUM |
| A domain cleanup issue was discovered in the C xenstore daemon (aka cxenstored) in Xen through 4.9.x. When shutting down a VM with a stubdomain, a race in cxenstored may cause a double-free. The xenstored daemon may crash, resulting in a DoS of any parts of the system relying on it (including domain creation / destruction, ballooning, device changes, etc.). | |||||
| CVE-2017-17563 | 1 Xen | 1 Xen | 2018-10-19 | 6.9 MEDIUM | 7.8 HIGH |
| An issue was discovered in Xen through 4.9.x allowing guest OS users to cause a denial of service (host OS crash) or gain host OS privileges by leveraging an incorrect mask for reference-count overflow checking in shadow mode. | |||||
| CVE-2017-15589 | 1 Xen | 1 Xen | 2018-10-19 | 2.1 LOW | 6.5 MEDIUM |
| An issue was discovered in Xen through 4.9.x allowing x86 HVM guest OS users to obtain sensitive information from the host OS (or an arbitrary guest OS) because intercepted I/O operations can cause a write of data from uninitialized hypervisor stack memory. | |||||
| CVE-2017-17046 | 1 Xen | 1 Xen | 2018-10-19 | 2.1 LOW | 6.5 MEDIUM |
| An issue was discovered in Xen through 4.9.x on the ARM platform allowing guest OS users to obtain sensitive information from DRAM after a reboot, because disjoint blocks, and physical addresses that do not start at zero, are mishandled. | |||||
| CVE-2016-4963 | 1 Xen | 1 Xen | 2018-09-07 | 1.9 LOW | 4.7 MEDIUM |
| The libxl device-handling in Xen through 4.6.x allows local guest OS users with access to the driver domain to cause a denial of service (management tool confusion) by manipulating information in the backend directories in xenstore. | |||||
