| 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-2015-2044 | 1 Xen | 1 Xen | 2025-04-12 | 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-2014-8594 | 3 Debian, Opensuse, Xen | 3 Debian Linux, Opensuse, Xen | 2025-04-12 | N/A |
| The do_mmu_update function in arch/x86/mm.c in Xen 4.x through 4.4.x does not properly restrict updates to only PV page tables, which allows remote PV guests to cause a denial of service (NULL pointer dereference) by leveraging hardware emulation services for HVM guests using Hardware Assisted Paging (HAP). | ||||
| CVE-2014-2580 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The netback driver in Xen, when using certain Linux versions that do not allow sleeping in softirq context, allows local guest administrators to cause a denial of service ("scheduling while atomic" error and host crash) via a malformed packet, which causes a mutex to be taken when trying to disable the interface. | ||||
| CVE-2014-2986 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The vgic_distr_mmio_write function in the virtual guest interrupt controller (GIC) distributor (arch/arm/vgic.c) in Xen 4.4.x, when running on an ARM system, allows local guest users to cause a denial of service (NULL pointer dereference and host crash) via unspecified vectors. | ||||
| CVE-2014-5148 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Xen 4.4.x, when running on an ARM system and "handling an unknown system register access from 64-bit userspace," returns to an instruction of the trap handler for kernel space faults instead of an instruction that is associated with faults in 64-bit userspace, which allows local guest users to cause a denial of service (crash) and possibly gain privileges via a crafted process. | ||||
| CVE-2014-3124 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The HVMOP_set_mem_type control in Xen 4.1 through 4.4.x allows local guest HVM administrators to cause a denial of service (hypervisor crash) or possibly execute arbitrary code by leveraging a separate qemu-dm vulnerability to trigger invalid page table translations for unspecified memory page types. | ||||
| 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-2014-3714 | 1 Xen | 1 Xen | 2025-04-12 | 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-2015-2150 | 3 Linux, Ubuntu, Xen | 3 Linux Kernel, Ubuntu, Xen | 2025-04-12 | N/A |
| Xen 3.3.x through 4.5.x and the Linux kernel through 3.19.1 do not properly restrict access to PCI command registers, which might allow local guest OS users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response. | ||||
| 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-2016-5242 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The p2m_teardown function in arch/arm/p2m.c in Xen 4.4.x through 4.6.x allows local guest OS users with access to the driver domain to cause a denial of service (NULL pointer dereference and host OS crash) by creating concurrent domains and holding references to them, related to VMID exhaustion. | ||||
| CVE-2016-7154 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Use-after-free vulnerability in the FIFO event channel code in Xen 4.4.x allows local guest OS administrators to cause a denial of service (host crash) and possibly execute arbitrary code or obtain sensitive information via an invalid guest frame number. | ||||
| CVE-2016-7094 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Buffer overflow in Xen 4.7.x and earlier allows local x86 HVM guest OS administrators on guests running with shadow paging to cause a denial of service via a pagetable update. | ||||
| 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-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-2015-5166 | 2 Fedoraproject, Xen | 2 Fedora, Xen | 2025-04-12 | N/A |
| Use-after-free vulnerability in QEMU in Xen 4.5.x and earlier does not completely unplug emulated block devices, which allows local HVM guest users to gain privileges by unplugging a block device twice. | ||||
| CVE-2016-3159 | 4 Debian, Fedoraproject, Oracle and 1 more | 4 Debian Linux, Fedora, Vm Server and 1 more | 2025-04-12 | N/A |
| 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-2016-7093 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Xen 4.5.3, 4.6.3, and 4.7.x allow local HVM guest OS administrators to overwrite hypervisor memory and consequently gain host OS privileges by leveraging mishandling of instruction pointer truncation during emulation. | ||||
