CVE-2012-4544 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
The PV domain builder in Xen 4.2 and earlier does not validate the size of the kernel or ramdisk (1) before or (2) after decompression, which allows local guest administrators to cause a denial of service (domain 0 memory consumption) via a crafted (a) kernel or (b) ramdisk. | ||||
CVE-2012-5510 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
Xen 4.x, when downgrading the grant table version, does not properly remove the status page from the tracking list when freeing the page, which allows local guest OS administrators to cause a denial of service (hypervisor crash) via unspecified vectors. | ||||

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-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-2011-1780 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
The instruction emulation in Xen 3.0.3 allows local SMP guest users to cause a denial of service (host crash) by replacing the instruction that causes the VM to exit in one thread with a different instruction in a different thread. | ||||
CVE-2011-1936 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
Xen, when using x86 Intel processors and the VMX virtualization extension is enabled, does not properly handle cpuid instruction emulation when exiting the VM, which allows local guest users to cause a denial of service (guest crash) via unspecified vectors. | ||||
CVE-2011-1166 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
Xen, possibly before 4.0.2, allows local 64-bit PV guests to cause a denial of service (host crash) by specifying user mode execution without user-mode pagetables. | ||||
CVE-2012-5515 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
The (1) XENMEM_decrease_reservation, (2) XENMEM_populate_physmap, and (3) XENMEM_exchange hypercalls in Xen 4.2 and earlier allow local guest administrators to cause a denial of service (long loop and hang) via a crafted extent_order value. | ||||
CVE-2012-5514 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
The guest_physmap_mark_populate_on_demand function in Xen 4.2 and earlier does not properly unlock the subject GFNs when checking if they are in use, which allows local guest HVM administrators to cause a denial of service (hang) via unspecified vectors. | ||||
CVE-2012-4538 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
The HVMOP_pagetable_dying hypercall in Xen 4.0, 4.1, and 4.2 does not properly check the pagetable state when running on shadow pagetables, which allows a local HVM guest OS to cause a denial of service (hypervisor crash) via unspecified vectors. | ||||
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-2012-5511 | 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-2012-3515 | 7 Canonical, Debian, Opensuse and 4 more | 15 Ubuntu Linux, Debian Linux, Opensuse and 12 more | 2025-04-11 | N/A |
Qemu, as used in Xen 4.0, 4.1 and possibly other products, when emulating certain devices with a virtual console backend, allows local OS guest users to gain privileges via a crafted escape VT100 sequence that triggers the overwrite of a "device model's address space." | ||||
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-2012-4539 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
Xen 4.0 through 4.2, when running 32-bit x86 PV guests on 64-bit hypervisors, allows local guest OS administrators to cause a denial of service (infinite loop and hang or crash) via invalid arguments to GNTTABOP_get_status_frames, aka "Grant table hypercall infinite loop DoS vulnerability." | ||||
CVE-2012-6032 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
Multiple integer overflows in the (1) tmh_copy_from_client and (2) tmh_copy_to_client functions 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 (memory corruption and host crash) via unspecified vectors. NOTE: this issue was originally published as part of CVE-2012-3497, which was too general; CVE-2012-3497 has been SPLIT into this ID and others. | ||||
CVE-2012-0217 | 9 Citrix, Freebsd, Illumos and 6 more | 13 Xenserver, Freebsd, Illumos and 10 more | 2025-04-11 | N/A |
The x86-64 kernel system-call functionality in Xen 4.1.2 and earlier, as used in Citrix XenServer 6.0.2 and earlier and other products; Oracle Solaris 11 and earlier; illumos before r13724; Joyent SmartOS before 20120614T184600Z; FreeBSD before 9.0-RELEASE-p3; NetBSD 6.0 Beta and earlier; Microsoft Windows Server 2008 R2 and R2 SP1 and Windows 7 Gold and SP1; and possibly other operating systems, when running on an Intel processor, incorrectly uses the sysret path in cases where a certain address is not a canonical address, which allows local users to gain privileges via a crafted application. NOTE: because this issue is due to incorrect use of the Intel specification, it should have been split into separate identifiers; however, there was some value in preserving the original mapping of the multi-codebase coordinated-disclosure effort to a single identifier. | ||||
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-2012-3516 | 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. |
