| CVE-2015-7814 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Race condition in the relinquish_memory function in arch/arm/domain.c in Xen 4.6.x and earlier allows local domains with partial management control to cause a denial of service (host crash) via vectors involving the destruction of a domain and using XENMEM_decrease_reservation to reduce the memory of the domain. | ||||
| CVE-2016-4480 | 2 Oracle, Xen | 2 Vm Server, Xen | 2025-04-12 | N/A |
| The guest_walk_tables function in arch/x86/mm/guest_walk.c in Xen 4.6.x and earlier does not properly handle the Page Size (PS) page table entry bit at the L4 and L3 page table levels, which might allow local guest OS users to gain privileges via a crafted mapping of memory. | ||||
| CVE-2015-7972 | 1 Xen | 1 Xen | 2025-04-12 | 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-2015-7971 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Xen 3.2.x through 4.6.x does not limit the number of printk console messages when logging certain pmu and profiling hypercalls, which allows local guests to cause a denial of service via a sequence of crafted (1) HYPERCALL_xenoprof_op hypercalls, which are not properly handled in the do_xenoprof_op function in common/xenoprof.c, or (2) HYPERVISOR_xenpmu_op hypercalls, which are not properly handled in the do_xenpmu_op function in arch/x86/cpu/vpmu.c. | ||||

| CVE-2014-1896 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The (1) do_send and (2) do_recv functions in io.c in libvchan in Xen 4.2.x, 4.3.x, and 4.4-RC series allows local guests to cause a denial of service or possibly gain privileges via crafted xenstore ring indexes, which triggers a "read or write past the end of the ring." | ||||
| CVE-2016-1570 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The PV superpage functionality in arch/x86/mm.c in Xen 3.4.0, 3.4.1, and 4.1.x through 4.6.x allows local PV guests to obtain sensitive information, cause a denial of service, gain privileges, or have unspecified other impact via a crafted page identifier (MFN) to the (1) MMUEXT_MARK_SUPER or (2) MMUEXT_UNMARK_SUPER sub-op in the HYPERVISOR_mmuext_op hypercall or (3) unknown vectors related to page table updates. | ||||
| CVE-2015-7835 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The mod_l2_entry function in arch/x86/mm.c in Xen 3.4 through 4.6.x does not properly validate level 2 page table entries, which allows local PV guest administrators to gain privileges via a crafted superpage mapping. | ||||
| CVE-2014-3968 | 2 Opensuse, Xen | 2 Opensuse, Xen | 2025-04-12 | N/A |
| The HVMOP_inject_msi function in Xen 4.2.x, 4.3.x, and 4.4.x allows local guest HVM administrators to cause a denial of service (host crash) via a large number of crafted requests, which trigger an error messages to be logged. | ||||
| CVE-2015-5154 | 5 Fedoraproject, Qemu, Redhat and 2 more | 10 Fedora, Qemu, Enterprise Linux and 7 more | 2025-04-12 | N/A |
| Heap-based buffer overflow in the IDE subsystem in QEMU, as used in Xen 4.5.x and earlier, when the container has a CDROM drive enabled, allows local guest users to execute arbitrary code on the host via unspecified ATAPI commands. | ||||
| CVE-2015-7813 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Xen 4.4.x, 4.5.x, and 4.6.x does not limit the number of printk console messages when reporting unimplemented hypercalls, which allows local guests to cause a denial of service via a sequence of (1) HYPERVISOR_physdev_op hypercalls, which are not properly handled in the do_physdev_op function in arch/arm/physdev.c, or (2) HYPERVISOR_hvm_op hypercalls, which are not properly handled in the do_hvm_op function in arch/arm/hvm.c. | ||||
| CVE-2014-3717 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Xen 4.4.x does not properly validate the load address for 64-bit ARM guest kernels, which allows local users to read system memory or cause a denial of service (crash) via a crafted kernel, which triggers a buffer overflow. | ||||
| CVE-2014-1892 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Xen 3.3 through 4.1, when XSM is enabled, allows local users to cause a denial of service via vectors related to a "large memory allocation," a different vulnerability than CVE-2014-1891, CVE-2014-1893, and CVE-2014-1894. | ||||
| CVE-2015-7969 | 1 Xen | 1 Xen | 2025-04-12 | 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-2014-3125 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Xen 4.4.x, when running on an ARM system, does not properly context switch the CNTKCTL_EL1 register, which allows local guest users to modify the hardware timers and cause a denial of service (crash) via unspecified vectors. | ||||

| The fpu_fxrstor function in arch/x86/i387.c in Xen 4.x does not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors, which allows local guest OS users to obtain sensitive register content information from another guest by leveraging pending exception and mask bits. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-2076. | ||||

| CVE-2014-5149 | 2 Opensuse, Xen | 2 Opensuse, Xen | 2025-04-12 | N/A |
| Certain MMU virtualization operations in Xen 4.2.x through 4.4.x, when using shadow pagetables, are not preemptible, which allows local HVM guest to cause a denial of service (vcpu consumption) by invoking these operations, which process every page assigned to a guest, a different vulnerability than CVE-2014-5146. | ||||
| CVE-2014-5148 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
