| CVE-2013-0151 | 1 Xen | 1 Xen | 2025-04-11 | 4.6 MEDIUM | 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. | |||||

| 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-2012-4535 | 1 Xen | 1 Xen | 2025-04-11 | 1.9 LOW | 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-2012-5634 | 1 Xen | 1 Xen | 2025-04-11 | 6.1 MEDIUM | 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-2012-0218 | 1 Xen | 1 Xen | 2025-04-11 | 1.9 LOW | 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-2013-2072 | 2 Debian, Xen | 2 Debian Linux, Xen | 2025-04-11 | 7.4 HIGH | 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-2013-3495 | 2 Opensuse, Xen | 2 Opensuse, Xen | 2025-04-11 | 4.7 MEDIUM | N/A |
| The Intel VT-d Interrupt Remapping engine in Xen 3.3.x through 4.3.x allows local guests to cause a denial of service (kernel panic) via a malformed Message Signaled Interrupt (MSI) from a PCI device that is bus mastering capable that triggers a System Error Reporting (SERR) Non-Maskable Interrupt (NMI). | |||||
| CVE-2012-3496 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-11 | 4.7 MEDIUM | 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-2012-6032 | 1 Xen | 1 Xen | 2025-04-11 | 4.9 MEDIUM | N/A |
| Multiple integer overflows in the (1) tmh_copy_from_client and (2) tmh_copy_to_client functions 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 (memory corruption and host crash) 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. | |||||
| CVE-2012-3498 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-11 | 5.6 MEDIUM | 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-2012-3494 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-11 | 2.1 LOW | 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-2011-1166 | 1 Xen | 1 Xen | 2025-04-11 | 5.5 MEDIUM | 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-2013-6375 | 2 Opensuse, Xen | 2 Opensuse, Xen | 2025-04-11 | 7.9 HIGH | N/A |
| Xen 4.2.x and 4.3.x, when using Intel VT-d for PCI passthrough, does not properly flush the TLB after clearing a present translation table entry, which allows local guest administrators to cause a denial of service or gain privileges via unspecified vectors related to an "inverted boolean parameter." | |||||
| CVE-2014-1642 | 1 Xen | 1 Xen | 2025-04-11 | 4.4 MEDIUM | 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-2013-4554 | 1 Xen | 1 Xen | 2025-04-11 | 5.2 MEDIUM | 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-2012-2934 | 1 Xen | 1 Xen | 2025-04-11 | 1.9 LOW | N/A |
