CVE-2015-4104 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
Xen 3.3.x through 4.5.x does not properly restrict access to PCI MSI mask bits, which allows local x86 HVM guest users to cause a denial of service (unexpected interrupt and host crash) via unspecified vectors. | ||||
CVE-2016-4963 | 1 Xen | 1 Xen | 2025-04-12 | N/A |

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-2016-6259 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-12 | N/A |
Xen 4.5.x through 4.7.x do not implement Supervisor Mode Access Prevention (SMAP) whitelisting in 32-bit exception and event delivery, which allows local 32-bit PV guest OS kernels to cause a denial of service (hypervisor and VM crash) by triggering a safety check. | ||||
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-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-2015-5166 | 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-2015-0361 | 2 Opensuse, Xen | 2 Opensuse, Xen | 2025-04-12 | N/A |
Use-after-free vulnerability in Xen 4.2.x, 4.3.x, and 4.4.x allows remote domains to cause a denial of service (system crash) via a crafted hypercall during HVM guest teardown. | ||||
CVE-2013-1964 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
Xen 4.0.x and 4.1.x incorrectly releases a grant reference when releasing a non-v1, non-transitive grant, which allows local guest administrators to cause a denial of service (host crash), obtain sensitive information, or possibly have other impacts via unspecified vectors. | ||||
CVE-2013-1922 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
qemu-nbd in QEMU, as used in Xen 4.2.x, determines the format of a raw disk image based on the header, which allows local guest OS administrators to read arbitrary files on the host by modifying the header to identify a different format, which is used when the guest is restarted, a different vulnerability than CVE-2008-2004. | ||||
CVE-2012-3494 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-11 | N/A |
The set_debugreg hypercall in include/asm-x86/debugreg.h in Xen 4.0, 4.1, and 4.2, and Citrix XenServer 6.0.2 and earlier, when running on x86-64 systems, allows local OS guest users to cause a denial of service (host crash) by writing to the reserved bits of the DR7 debug control register. | ||||
CVE-2013-1919 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
Xen 4.2.x and 4.1.x does not properly restrict access to IRQs, which allows local stub domain clients to gain access to IRQs and cause a denial of service via vectors related to "passed-through IRQs or PCI devices." | ||||
CVE-2013-1917 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
Xen 3.1 through 4.x, when running 64-bit hosts on Intel CPUs, does not clear the NT flag when using an IRET after a SYSENTER instruction, which allows PV guest users to cause a denial of service (hypervisor crash) by triggering a #GP fault, which is not properly handled by another IRET instruction. | ||||
CVE-2012-3433 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
Xen 4.0 and 4.1 allows local HVM guest OS kernels to cause a denial of service (domain 0 VCPU hang and kernel panic) by modifying the physical address space in a way that triggers excessive shared page search time during the p2m teardown. | ||||
CVE-2013-1442 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
Xen 4.0 through 4.3.x, when using AVX or LWP capable CPUs, does not properly clear previous data from registers when using an XSAVE or XRSTOR to extend the state components of a saved or restored vCPU after touching other restored extended registers, which allows local guest OSes to obtain sensitive information by reading the registers. | ||||
CVE-2013-1432 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
Xen 4.1.x and 4.2.x, when the XSA-45 patch is in place, does not properly maintain references on pages stored for deferred cleanup, which allows local PV guest kernels to cause a denial of service (premature page free and hypervisor crash) or possibly gain privileges via unspecified vectors. | ||||
CVE-2013-0215 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
oxenstored in Xen 4.1.x, Xen 4.2.x, and xen-unstable does not properly consider the state of the Xenstore ring during read operations, which allows guest OS users to cause a denial of service (daemon crash and host-control outage, or memory consumption) or obtain sensitive control-plane data by leveraging guest administrative access. | ||||
CVE-2013-0154 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
The get_page_type function in xen/arch/x86/mm.c in Xen 4.2, when debugging is enabled, allows local PV or HVM guest administrators to cause a denial of service (assertion failure and hypervisor crash) via unspecified vectors related to a hypercall. | ||||
CVE-2012-3432 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
The handle_mmio function in arch/x86/hvm/io.c in the MMIO operations emulator for Xen 3.3 and 4.x, when running an HVM guest, does not properly reset certain state information between emulation cycles, which allows local guest OS users to cause a denial of service (guest OS crash) via unspecified operations on MMIO regions. | ||||
CVE-2012-2934 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
Xen 4.0, and 4.1, when running a 64-bit PV guest on "older" AMD CPUs, does not properly protect against a certain AMD processor bug, which allows local guest OS users to cause a denial of service (host hang) via sequential execution of instructions across a non-canonical boundary, a different vulnerability than CVE-2012-0217. |
