CVE-2011-3131 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
Xen 4.1.1 and earlier allows local guest OS kernels with control of a PCI[E] device to cause a denial of service (CPU consumption and host hang) via many crafted DMA requests that are denied by the IOMMU, which triggers a livelock. | ||||
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 |

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-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-2012-3498 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-11 | N/A |
PHYSDEVOP_map_pirq in Xen 4.1 and 4.2 and Citrix XenServer 6.0.2 and earlier allows local HVM guest OS kernels to cause a denial of service (host crash) and possibly read hypervisor or guest memory via vectors related to a missing range check of map->index. | ||||
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-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-2012-4535 | 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-2012-4536 | 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-2012-4537 | 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-2012-4539 | 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-2012-4544 | 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-2012-5511 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
