| CVE-2013-1432 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.1.x and 4.2.x, when the XSA-45 patch is in place, does not properly maintain references on pages stored for deferred cleanup, which allows local PV guest kernels to cause a denial of service (premature page free and hypervisor crash) or possibly gain privileges via unspecified vectors. | ||||
| CVE-2013-0231 | 3 Linux, Redhat, Xen | 3 Linux Kernel, Enterprise Linux, Xen | 2025-04-11 | 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-2012-6034 | 1 Xen | 1 Xen | 2025-04-11 | 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-2012-6032 | 1 Xen | 1 Xen | 2025-04-11 | 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-2012-5510 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.x, when downgrading the grant table version, does not properly remove the status page from the tracking list when freeing the page, which allows local guest OS administrators to cause a denial of service (hypervisor crash) via unspecified vectors. | ||||
| CVE-2012-4544 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | 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-2012-4539 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.0 through 4.2, when running 32-bit x86 PV guests on 64-bit hypervisors, allows local guest OS administrators to cause a denial of service (infinite loop and hang or crash) via invalid arguments to GNTTABOP_get_status_frames, aka "Grant table hypercall infinite loop DoS vulnerability." | ||||
| 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-2012-4537 | 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-2012-4536 | 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-2012-4535 | 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-2012-3498 | 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-2012-3495 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-11 | 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-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. | ||||
| CVE-2007-6416 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-09 | N/A |

| CVE-2007-5730 | 4 Debian, Qemu, Redhat and 1 more | 4 Debian Linux, Qemu, Enterprise Linux and 1 more | 2025-04-09 | N/A |
| Heap-based buffer overflow in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to execute arbitrary code via crafted data in the "net socket listen" option, aka QEMU "net socket" heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of "NE2000 network driver and the socket code," but this is the correct identifier for the individual net socket listen vulnerability. | ||||
| CVE-2007-0998 | 2 Redhat, Xen | 3 Enterprise Linux, Fedora Core, Qemu | 2025-04-09 | N/A |
| The VNC server implementation in QEMU, as used by Xen and possibly other environments, allows local users of a guest operating system to read arbitrary files on the host operating system via unspecified vectors related to QEMU monitor mode, as demonstrated by mapping files to a CDROM device. NOTE: some of these details are obtained from third party information. | ||||
| CVE-2009-3525 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-09 | N/A |
| The pyGrub boot loader in Xen 3.0.3, 3.3.0, and Xen-3.3.1 does not support the password option in grub.conf for para-virtualized guests, which allows attackers with access to the para-virtualized guest console to boot the guest or modify the guest's kernel boot parameters without providing the expected password. | ||||
| CVE-2009-1758 | 3 Linux, Redhat, Xen | 3 Linux Kernel, Enterprise Linux, Xen | 2025-04-09 | N/A |
| The hypervisor_callback function in Xen, possibly before 3.4.0, as applied to the Linux kernel 2.6.30-rc4, 2.6.18, and probably other versions allows guest user applications to cause a denial of service (kernel oops) of the guest OS by triggering a segmentation fault in "certain address ranges." | ||||
| CVE-2008-4993 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-09 | N/A |
| qemu-dm.debug in Xen 3.2.1 allows local users to overwrite arbitrary files via a symlink attack on the /tmp/args temporary file. | ||||
