| CVE-2014-1666 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The do_physdev_op function in Xen 4.1.5, 4.1.6.1, 4.2.2 through 4.2.3, and 4.3.x does not properly restrict access to the (1) PHYSDEVOP_prepare_msix and (2) PHYSDEVOP_release_msix operations, which allows local PV guests to cause a denial of service (host or guest malfunction) or possibly gain privileges via unspecified vectors. | ||||
| CVE-2013-4554 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
| Xen 3.0.3 through 4.1.x (possibly 4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1) does not properly prevent access to hypercalls, which allows local guest users to gain privileges via a crafted application running in ring 1 or 2. | ||||
| 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-2013-4551 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.2.x and 4.3.x, when nested virtualization is disabled, does not properly check the emulation paths for (1) VMLAUNCH and (2) VMRESUME, which allows local HVM guest users to cause a denial of service (host crash) via unspecified vectors related to "guest VMX instruction execution." | ||||
| CVE-2013-4494 | 3 Debian, Redhat, Xen | 3 Debian Linux, Enterprise Linux, Xen | 2025-04-11 | N/A |
| Xen before 4.1.x, 4.2.x, and 4.3.x does not take the page_alloc_lock and grant_table.lock in the same order, which allows local guest administrators with access to multiple vcpus to cause a denial of service (host deadlock) via unspecified vectors. | ||||
| 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-2013-3495 | 2 Opensuse, Xen | 2 Opensuse, Xen | 2025-04-11 | N/A |
| The Intel VT-d Interrupt Remapping engine in Xen 3.3.x through 4.3.x allows local guests to cause a denial of service (kernel panic) via a malformed Message Signaled Interrupt (MSI) from a PCI device that is bus mastering capable that triggers a System Error Reporting (SERR) Non-Maskable Interrupt (NMI). | ||||
| CVE-2013-1952 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.x, when using Intel VT-d for a bus mastering capable PCI device, does not properly check the source when accessing a bridge device's interrupt remapping table entries for MSI interrupts, which allows local guest domains to cause a denial of service (interrupt injection) via unspecified vectors. | ||||
| CVE-2013-0231 | 3 Linux, Redhat, Xen | 3 Linux Kernel, Enterprise Linux, Xen | 2025-04-11 | N/A |
| The pciback_enable_msi function in the PCI backend driver (drivers/xen/pciback/conf_space_capability_msi.c) in Xen for the Linux kernel 2.6.18 and 3.8 allows guest OS users with PCI device access to cause a denial of service via a large number of kernel log messages. NOTE: some of these details are obtained from third party information. | ||||
| CVE-2013-0153 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
| The AMD IOMMU support in Xen 4.2.x, 4.1.x, 3.3, and other versions, when using AMD-Vi for PCI passthrough, uses the same interrupt remapping table for the host and all guests, which allows guests to cause a denial of service by injecting an interrupt into other guests. | ||||
| CVE-2013-4416 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The Ocaml xenstored implementation (oxenstored) in Xen 4.1.x, 4.2.x, and 4.3.x allows local guest domains to cause a denial of service (domain shutdown) via a large message reply. | ||||
| CVE-2013-4375 | 2 Qemu, Xen | 2 Qemu, Xen | 2025-04-11 | N/A |
| The qdisk PV disk backend in qemu-xen in Xen 4.2.x and 4.3.x before 4.3.1, and qemu 1.1 and other versions, allows local HVM guests to cause a denial of service (domain grant reference consumption) via unspecified vectors. | ||||
| 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-2013-4371 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Use-after-free vulnerability in the libxl_list_cpupool function in the libxl toolstack library in Xen 4.2.x and 4.3.x, when running "under memory pressure," returns the original pointer when the realloc function fails, which allows local users to cause a denial of service (heap corruption and crash) and possibly execute arbitrary code via unspecified vectors. | ||||
| CVE-2013-4368 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
| The outs instruction emulation in Xen 3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or GS: segment override, uses an uninitialized variable as a segment base, which allows local 64-bit PV guests to obtain sensitive information (hypervisor stack content) via unspecified vectors related to stale data in a segment register. | ||||
| 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. | ||||
| CVE-2013-4356 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.3.x writes hypervisor mappings to certain shadow pagetables when live migration is performed on hosts with more than 5TB of RAM, which allows local 64-bit PV guests to read or write to invalid memory and cause a denial of service (crash). | ||||
| CVE-2013-4355 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
| Xen 4.3.x and earlier does not properly handle certain errors, which allows local HVM guests to obtain hypervisor stack memory via a (1) port or (2) memory mapped I/O write or (3) other unspecified operations related to addresses without associated memory. | ||||
| CVE-2013-4329 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The xenlight library (libxl) in Xen 4.0.x through 4.2.x, when IOMMU is disabled, provides access to a busmastering-capable PCI passthrough device before the IOMMU setup is complete, which allows local HVM guest domains to gain privileges or cause a denial of service via a DMA instruction. | ||||
| CVE-2013-2212 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The vmx_set_uc_mode function in Xen 3.3 through 4.3, when disabling caches, allows local HVM guests with access to memory mapped I/O regions to cause a denial of service (CPU consumption and possibly hypervisor or guest kernel panic) via a crafted GFN range. | ||||
