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-2013-1920 1 Xen 1 Xen 2025-04-11 N/A
Xen 4.2.x, 4.1.x, and earlier, when the hypervisor is running "under memory pressure" and the Xen Security Module (XSM) is enabled, uses the wrong ordering of operations when extending the per-domain event channel tracking table, which causes a use-after-free and allows local guest kernels to inject arbitrary events and 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-2013-4361 1 Xen 1 Xen 2025-04-11 N/A
The fbld instruction emulation in Xen 3.3.x through 4.3.x does not use the correct variable for the source effective address, which allows local HVM guests to obtain hypervisor stack information by reading the values used by the instruction.
CVE-2013-1918 1 Xen 1 Xen 2025-04-11 N/A
Certain page table manipulation operations in Xen 4.1.x, 4.2.x, and earlier are not preemptible, which allows local PV kernels to cause a denial of service via vectors related to "deep page table traversal."
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-2013-1917 1 Xen 1 Xen 2025-04-11 N/A
Xen 3.1 through 4.x, when running 64-bit hosts on Intel CPUs, does not clear the NT flag when using an IRET after a SYSENTER instruction, which allows PV guest users to cause a denial of service (hypervisor crash) by triggering a #GP fault, which is not properly handled by another IRET instruction.
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-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-2013-1919 1 Xen 1 Xen 2025-04-11 N/A
Xen 4.2.x and 4.1.x does not properly restrict access to IRQs, which allows local stub domain clients to gain access to IRQs and cause a denial of service via vectors related to "passed-through IRQs or PCI devices."
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-2012-3516 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-2012-5513 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-2013-6400 1 Xen 1 Xen 2025-04-11 N/A
Xen 4.2.x and 4.3.x, when using Intel VT-d and a PCI device has been assigned, does not clear the flag that suppresses IOMMU TLB flushes when unspecified errors occur, which causes the TLB entries to not be flushed and allows local guest administrators to cause a denial of service (host crash) or gain privileges 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-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-2012-6030 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-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-2013-4370 1 Xen 1 Xen 2025-04-11 N/A
The ocaml binding for the xc_vcpu_getaffinity function in Xen 4.2.x and 4.3.x frees certain memory that may still be intended for use, which allows local users to cause a denial of service (heap corruption and crash) and possibly execute arbitrary code via unspecified vectors that trigger a (1) use-after-free or (2) double free.
CVE-2012-6333 1 Xen 1 Xen 2025-04-11 N/A
Multiple HVM control operations in Xen 3.4 through 4.2 allow local HVM guest OS administrators to cause a denial of service (physical CPU consumption) via a large input.
