CVE-2011-2519 2 Redhat, Xen 6 Enterprise Linux, Enterprise Linux Desktop, Enterprise Linux Server and 3 more 2025-04-11 N/A
Xen in the Linux kernel, when running a guest on a host without hardware assisted paging (HAP), allows guest users to cause a denial of service (invalid pointer dereference and hypervisor crash) via the SAHF instruction.
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-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-2012-3515 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-2012-4537 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-2012-5515 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-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-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-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-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-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-2012-4535 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-2012-4411 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.
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-2012-4536 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-2012-4538 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-2012-3496 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.
