| CVE-2013-1918 | 1 Xen | 1 Xen | 2025-04-11 | 4.7 MEDIUM | 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-2013-4355 | 1 Xen | 1 Xen | 2025-04-11 | 1.5 LOW | 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-2013-4551 | 1 Xen | 1 Xen | 2025-04-11 | 5.7 MEDIUM | N/A |
| Xen 4.2.x and 4.3.x, when nested virtualization is disabled, does not properly check the emulation paths for (1) VMLAUNCH and (2) VMRESUME, which allows local HVM guest users to cause a denial of service (host crash) via unspecified vectors related to "guest VMX instruction execution." | |||||
| CVE-2012-6030 | 1 Xen | 1 Xen | 2025-04-11 | 7.2 HIGH | 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-2013-0153 | 1 Xen | 1 Xen | 2025-04-11 | 4.7 MEDIUM | N/A |
| The AMD IOMMU support in Xen 4.2.x, 4.1.x, 3.3, and other versions, when using AMD-Vi for PCI passthrough, uses the same interrupt remapping table for the host and all guests, which allows guests to cause a denial of service by injecting an interrupt into other guests. | |||||
| CVE-2012-4544 | 1 Xen | 1 Xen | 2025-04-11 | 2.1 LOW | 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-2013-2195 | 1 Xen | 1 Xen | 2025-04-11 | 6.9 MEDIUM | N/A |
| The Elf parser (libelf) in Xen 4.2.x and earlier allow local guest administrators with certain permissions to have an unspecified impact via a crafted kernel, related to "pointer dereferences" involving unexpected calculations. | |||||
| CVE-2013-0231 | 2 Linux, Xen | 2 Linux Kernel, Xen | 2025-04-11 | 4.9 MEDIUM | 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-2012-4538 | 1 Xen | 1 Xen | 2025-04-11 | 4.9 MEDIUM | 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-2013-4356 | 1 Xen | 1 Xen | 2025-04-11 | 5.4 MEDIUM | N/A |
| Xen 4.3.x writes hypervisor mappings to certain shadow pagetables when live migration is performed on hosts with more than 5TB of RAM, which allows local 64-bit PV guests to read or write to invalid memory and cause a denial of service (crash). | |||||
| CVE-2013-2212 | 1 Xen | 1 Xen | 2025-04-11 | 5.7 MEDIUM | N/A |
| The vmx_set_uc_mode function in Xen 3.3 through 4.3, when disabling caches, allows local HVM guests with access to memory mapped I/O regions to cause a denial of service (CPU consumption and possibly hypervisor or guest kernel panic) via a crafted GFN range. | |||||
| CVE-2013-2076 | 1 Xen | 1 Xen | 2025-04-11 | 4.3 MEDIUM | N/A |
| Xen 4.0.x, 4.1.x, and 4.2.x, when running on AMD64 processors, only save/restore the FOP, FIP, and FDP x87 registers in FXSAVE/FXRSTOR when an exception is pending, which allows one domain to determine portions of the state of floating point instructions of other domains, which can be leveraged to obtain sensitive information such as cryptographic keys, a similar vulnerability to CVE-2006-1056. NOTE: this is the documented behavior of AMD64 processors, but it is inconsistent with Intel processors in a security-relevant fashion that was not addressed by the kernels. | |||||
| CVE-2014-1950 | 1 Xen | 1 Xen | 2025-04-11 | 4.6 MEDIUM | N/A |
| Use-after-free vulnerability in the xc_cpupool_getinfo function in Xen 4.1.x through 4.3.x, when using a multithreaded toolstack, does not properly handle a failure by the xc_cpumap_alloc function, which allows local users with access to management functions to cause a denial of service (heap corruption) and possibly gain privileges via unspecified vectors. | |||||
| CVE-2012-6031 | 1 Xen | 1 Xen | 2025-04-11 | 4.7 MEDIUM | N/A |
| The do_tmem_get 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 (CPU hang and host crash) via unspecified vectors related to a spinlock being held in the "bad_copy 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-2013-0154 | 1 Xen | 1 Xen | 2025-04-11 | 1.9 LOW | N/A |
| The get_page_type function in xen/arch/x86/mm.c in Xen 4.2, when debugging is enabled, allows local PV or HVM guest administrators to cause a denial of service (assertion failure and hypervisor crash) via unspecified vectors related to a hypercall. | |||||
| CVE-2011-1936 | 1 Xen | 1 Xen | 2025-04-11 | 4.6 MEDIUM | N/A |
| Xen, when using x86 Intel processors and the VMX virtualization extension is enabled, does not properly handle cpuid instruction emulation when exiting the VM, which allows local guest users to cause a denial of service (guest crash) via unspecified vectors. | |||||
| CVE-2012-6034 | 1 Xen | 1 Xen | 2025-04-11 | 4.4 MEDIUM | N/A |
| The (1) tmemc_save_get_next_page and (2) tmemc_save_get_next_inv functions and the (3) TMEMC_SAVE_GET_POOL_UUID sub-operation in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 "do not check incoming guest output buffer pointers," which allows local guest OS users to cause a denial of service (memory corruption and host crash) or 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. | |||||
| CVE-2012-5525 | 1 Xen | 1 Xen | 2025-04-11 | 4.7 MEDIUM | 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-2013-1922 | 1 Xen | 1 Xen | 2025-04-11 | 3.3 LOW | N/A |
| qemu-nbd in QEMU, as used in Xen 4.2.x, determines the format of a raw disk image based on the header, which allows local guest OS administrators to read arbitrary files on the host by modifying the header to identify a different format, which is used when the guest is restarted, a different vulnerability than CVE-2008-2004. | |||||
| CVE-2013-4371 | 1 Xen | 1 Xen | 2025-04-11 | 4.4 MEDIUM | N/A |
| Use-after-free vulnerability in the libxl_list_cpupool function in the libxl toolstack library in Xen 4.2.x and 4.3.x, when running "under memory pressure," returns the original pointer when the realloc function fails, which allows local users to cause a denial of service (heap corruption and crash) and possibly execute arbitrary code via unspecified vectors. | |||||
