CVE-2012-3495 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-11 | 6.1 MEDIUM | 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-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-2012-4537 | 1 Xen | 1 Xen | 2025-04-11 | 2.1 LOW | 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-2011-3131 | 1 Xen | 1 Xen | 2025-04-11 | 4.6 MEDIUM | N/A |
Xen 4.1.1 and earlier allows local guest OS kernels with control of a PCI[E] device to cause a denial of service (CPU consumption and host hang) via many crafted DMA requests that are denied by the IOMMU, which triggers a livelock. | |||||
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-2013-2194 | 1 Xen | 1 Xen | 2025-04-11 | 6.9 MEDIUM | N/A |
Multiple integer overflows in 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. | |||||
CVE-2012-4536 | 1 Xen | 1 Xen | 2025-04-11 | 2.1 LOW | 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-2012-6032 | 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-2012-6031 | 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. | |||||
