| 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. | ||||
| CVE-2015-3456 | 3 Qemu, Redhat, Xen | 7 Qemu, Enterprise Linux, Enterprise Virtualization and 4 more | 2025-04-12 | N/A |
| The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM. | ||||
| CVE-2015-8550 | 2 Novell, Xen | 2 Suse Linux Enterprise Real Time Extension, Xen | 2025-04-12 | N/A |
| Xen, when used on a system providing PV backends, allows local guest OS administrators to cause a denial of service (host OS crash) or gain privileges by writing to memory shared between the frontend and backend, aka a double fetch vulnerability. | ||||
| 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-2015-4105 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Xen 3.3.x through 4.5.x enables logging for PCI MSI-X pass-through error messages, which allows local x86 HVM guests to cause a denial of service (host disk consumption) via certain invalid operations. | ||||
| CVE-2016-7092 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The get_page_from_l3e function in arch/x86/mm.c in Xen allows local 32-bit PV guest OS administrators to gain host OS privileges via vectors related to L3 recursive pagetables. | ||||
| CVE-2014-5147 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Xen 4.4.x, when running a 64-bit kernel on an ARM system, does not properly handle traps from the guest domain that use a different address width, which allows local guest users to cause a denial of service (host crash) via a crafted 32-bit process. | ||||
| 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-2015-7970 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The p2m_pod_emergency_sweep function in arch/x86/mm/p2m-pod.c in Xen 3.4.x, 3.5.x, and 3.6.x is not preemptible, which allows local x86 HVM guest administrators to cause a denial of service (CPU consumption and possibly reboot) via crafted memory contents that triggers a "time-consuming linear scan," related to Populate-on-Demand. | ||||
| 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. | ||||

| The HVMOP_set_mem_access HVM control operations in Xen 4.1.x for 32-bit and 4.1.x through 4.4.x for 64-bit allow local guest administrators to cause a denial of service (CPU consumption) by leveraging access to certain service domains for HVM guests and a large input. | ||||
| CVE-2014-3715 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Buffer overflow in Xen 4.4.x allows local users to read system memory or cause a denial of service (crash) via a crafted 32-bit guest kernel, related to searching for an appended DTB. | ||||
| CVE-2015-6654 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
