| CVE-2012-6030 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The do_tmem_op function 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 (host crash) and possibly have other unspecified impacts via unspecified vectors related to "broken locking checks" in an "error path." 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-2012-5634 | 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-2013-2072 | 2 Debian, Xen | 2 Debian Linux, Xen | 2025-04-11 | N/A |
| Buffer overflow in the Python bindings for the xc_vcpu_setaffinity call in Xen 4.0.x, 4.1.x, and 4.2.x allows local administrators with permissions to configure VCPU affinity to cause a denial of service (memory corruption and xend toolstack crash) and possibly gain privileges via a crafted cpumap. | ||||
| 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-2012-2625 | 2 Redhat, Xen | 3 Enterprise Linux, Xen, Xen-unstable | 2025-04-11 | N/A |
| The PyGrub boot loader in Xen unstable before changeset 25589:60f09d1ab1fe, 4.2.x, and 4.1.x allows local para-virtualized guest users to cause a denial of service (memory consumption) via a large (1) bzip2 or (2) lzma compressed kernel image. | ||||
| 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-2012-5525 | 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-2012-5514 | 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-2012-5513 | 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-2013-4369 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The xlu_vif_parse_rate function in the libxlu library in Xen 4.2.x and 4.3.x allows local users to cause a denial of service (NULL pointer dereference) by using the "@" character as the VIF rate configuration. | ||||
| 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-2012-4539 | 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-2012-4538 | 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-2012-4537 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
| Xen 3.4 through 4.2, and possibly earlier versions, does not properly synchronize the p2m and m2p tables when the set_p2m_entry function fails, which allows local HVM guest OS administrators to cause a denial of service (memory consumption and assertion failure), aka "Memory mapping failure DoS vulnerability." | ||||
| CVE-2012-4536 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The (1) domain_pirq_to_emuirq and (2) physdev_unmap_pirq functions in Xen 2.2 allows local guest OS administrators to cause a denial of service (Xen crash) via a crafted pirq value that triggers an out-of-bounds read. | ||||
| CVE-2012-4535 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
| Xen 3.4 through 4.2, and possibly earlier versions, allows local guest OS administrators to cause a denial of service (Xen infinite loop and physical CPU consumption) by setting a VCPU with an "inappropriate deadline." | ||||
| 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. | ||||
