| CVE-2014-1950 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Use-after-free vulnerability in the xc_cpupool_getinfo function in Xen 4.1.x through 4.3.x, when using a multithreaded toolstack, does not properly handle a failure by the xc_cpumap_alloc function, which allows local users with access to management functions to cause a denial of service (heap corruption) and possibly gain privileges 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-2012-3495 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-11 | N/A |
| The physdev_get_free_pirq hypercall in arch/x86/physdev.c in Xen 4.1.x and Citrix XenServer 6.0.2 and earlier uses the return value of the get_free_pirq function as an array index without checking that the return value indicates an error, which allows guest OS users to cause a denial of service (invalid memory write and host crash) and possibly gain privileges via unspecified vectors. | ||||
| CVE-2012-3496 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-11 | N/A |
| XENMEM_populate_physmap in Xen 4.0, 4.1, and 4.2, and Citrix XenServer 6.0.2 and earlier, when translating paging mode is not used, allows local PV OS guest kernels to cause a denial of service (BUG triggered and host crash) via invalid flags such as MEMF_populate_on_demand. | ||||
| CVE-2012-3497 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| (1) TMEMC_SAVE_GET_CLIENT_WEIGHT, (2) TMEMC_SAVE_GET_CLIENT_CAP, (3) TMEMC_SAVE_GET_CLIENT_FLAGS and (4) TMEMC_SAVE_END in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 allow local guest OS users to cause a denial of service (NULL pointer dereference or memory corruption and host crash) or possibly have other unspecified impacts via a NULL client id. | ||||
| CVE-2012-3516 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-11 | N/A |
| The GNTTABOP_swap_grant_ref sub-operation in the grant table hypercall in Xen 4.2 and Citrix XenServer 6.0.2 allows local guest kernels or administrators to cause a denial of service (host crash) and possibly gain privileges via a crafted grant reference that triggers a write to an arbitrary hypervisor memory location. | ||||
| CVE-2013-4553 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The XEN_DOMCTL_getmemlist hypercall in Xen 3.4.x through 4.3.x (possibly 4.3.1) does not always obtain the page_alloc_lock and mm_rwlock in the same order, which allows local guest administrators to cause a denial of service (host deadlock). | ||||
| CVE-2011-1763 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
| The get_free_port function in Xen allows local authenticated DomU users to cause a denial of service or possibly gain privileges via unspecified vectors involving a new event channel port. | ||||
| CVE-2011-2901 | 2 Redhat, Xen | 3 Enterprise Linux, Rhel Eus, Xen | 2025-04-11 | N/A |
| Off-by-one error in the __addr_ok macro in Xen 3.3 and earlier allows local 64 bit PV guest administrators to cause a denial of service (host crash) via unspecified hypercalls that ignore virtual-address bits. | ||||
| CVE-2012-4411 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The graphical console in Xen 4.0, 4.1 and 4.2 allows local OS guest administrators to obtain sensitive host resource information via the qemu monitor. NOTE: this might be a duplicate of CVE-2007-0998. | ||||
| CVE-2012-0218 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 3.4, 4.0, and 4.1, when the guest OS has not registered a handler for a syscall or sysenter instruction, does not properly clear a flag for exception injection when injecting a General Protection Fault, which allows local PV guest OS users to cause a denial of service (guest crash) by later triggering an exception that would normally be handled within Xen. | ||||
| 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-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-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-2012-5511 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Stack-based buffer overflow in the dirty video RAM tracking functionality in Xen 3.4 through 4.1 allows local HVM guest OS administrators to cause a denial of service (crash) via a large bitmap image. | ||||
| CVE-2012-5513 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
| The XENMEM_exchange handler in Xen 4.2 and earlier does not properly check the memory address, which allows local PV guest OS administrators to cause a denial of service (crash) or possibly gain privileges via unspecified vectors that overwrite memory in the hypervisor reserved range. | ||||
| CVE-2012-5525 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The get_page_from_gfn hypercall function in Xen 4.2 allows local PV guest OS administrators to cause a denial of service (crash) via a crafted GFN that triggers a buffer over-read. | ||||
| CVE-2012-5634 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.2.x, 4.1.x, and 4.0, when using Intel VT-d for PCI passthrough, does not properly configure VT-d when supporting a device that is behind a legacy PCI Bridge, which allows local guests to cause a denial of service to other guests by injecting an interrupt. | ||||
| CVE-2007-6416 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-09 | N/A |
| The copy_to_user function in the PAL emulation functionality for Xen 3.1.2 and earlier, when running on ia64 systems, allows HVM guest users to access arbitrary physical memory by triggering certain mapping operations. | ||||
