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-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-2012-4535 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-2012-2934 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-2011-1763 2 Redhat, Xen 2 Enterprise Linux, Xen 2025-04-11 N/A
The get_free_port function in Xen allows local authenticated DomU users to cause a denial of service or possibly gain privileges via unspecified vectors involving a new event channel port.
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-2014-1642 1 Xen 1 Xen 2025-04-11 N/A
The IRQ setup in Xen 4.2.x and 4.3.x, when using device passthrough and configured to support a large number of CPUs, frees certain memory that may still be intended for use, which allows local guest administrators to cause a denial of service (memory corruption and hypervisor crash) and possibly execute arbitrary code via vectors related to an out-of-memory error that triggers a (1) use-after-free or (2) double free.
CVE-2013-0152 1 Xen 1 Xen 2025-04-11 N/A
Memory leak in Xen 4.2 and unstable allows local HVM guests to cause a denial of service (host memory consumption) by performing nested virtualization in a way that triggers errors that are not properly handled.
CVE-2013-0151 1 Xen 1 Xen 2025-04-11 N/A
The do_hvm_op function in xen/arch/x86/hvm/hvm.c in Xen 4.2.x on the x86_32 platform does not prevent HVM_PARAM_NESTEDHVM (aka nested virtualization) operations, which allows guest OS users to cause a denial of service (long-duration page mappings and host OS crash) by leveraging administrative access to an HVM guest in a domain with a large number of VCPUs.
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.
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-2013-4554 2 Redhat, Xen 2 Enterprise Linux, Xen 2025-04-11 N/A
Xen 3.0.3 through 4.1.x (possibly 4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1) does not properly prevent access to hypercalls, which allows local guest users to gain privileges via a crafted application running in ring 1 or 2.
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-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-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-2013-4355 2 Redhat, Xen 2 Enterprise Linux, Xen 2025-04-11 N/A
Xen 4.3.x and earlier does not properly handle certain errors, which allows local HVM guests to obtain hypervisor stack memory via a (1) port or (2) memory mapped I/O write or (3) other unspecified operations related to addresses without associated memory.
CVE-2013-2211 1 Xen 1 Xen 2025-04-11 N/A
The libxenlight (libxl) toolstack library in Xen 4.0.x, 4.1.x, and 4.2.x uses weak permissions for xenstore keys for paravirtualised and emulated serial console devices, which allows local guest administrators to modify the xenstore value via unspecified vectors.
CVE-2013-2078 1 Xen 1 Xen 2025-04-11 N/A
Xen 4.0.2 through 4.0.4, 4.1.x, and 4.2.x allows local PV guest users to cause a denial of service (hypervisor crash) via certain bit combinations to the XSETBV instruction.
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-2012-6036 1 Xen 1 Xen 2025-04-11 N/A
The (1) memc_save_get_next_page, (2) tmemc_restore_put_page and (3) tmemc_restore_flush_page functions in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 do not check for negative id pools, which allows local guest OS users to cause a denial of service (memory corruption and host crash) or possibly execute arbitrary code 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.
