CVE-2015-5154 5 Fedoraproject, Qemu, Redhat and 2 more 10 Fedora, Qemu, Enterprise Linux and 7 more 2025-04-12 N/A
Heap-based buffer overflow in the IDE subsystem in QEMU, as used in Xen 4.5.x and earlier, when the container has a CDROM drive enabled, allows local guest users to execute arbitrary code on the host via unspecified ATAPI commands.
CVE-2015-4164 1 Xen 1 Xen 2025-04-12 N/A
The compat_iret function in Xen 3.1 through 4.5 iterates the wrong way through a loop, which allows local 32-bit PV guest administrators to cause a denial of service (large loop and system hang) via a hypercall_iret call with EFLAGS.VM set.
CVE-2015-4163 1 Xen 1 Xen 2025-04-12 N/A
GNTTABOP_swap_grant_ref in Xen 4.2 through 4.5 does not check the grant table operation version, which allows local guest domains to cause a denial of service (NULL pointer dereference) via a hypercall without a GNTTABOP_setup_table or GNTTABOP_set_version.
CVE-2015-4105 1 Xen 1 Xen 2025-04-12 N/A
Xen 3.3.x through 4.5.x enables logging for PCI MSI-X pass-through error messages, which allows local x86 HVM guests to cause a denial of service (host disk consumption) via certain invalid operations.
CVE-2015-4104 1 Xen 1 Xen 2025-04-12 N/A
Xen 3.3.x through 4.5.x does not properly restrict access to PCI MSI mask bits, which allows local x86 HVM guest users to cause a denial of service (unexpected interrupt and host crash) via unspecified vectors.
CVE-2015-7970 1 Xen 1 Xen 2025-04-12 N/A
The p2m_pod_emergency_sweep function in arch/x86/mm/p2m-pod.c in Xen 3.4.x, 3.5.x, and 3.6.x is not preemptible, which allows local x86 HVM guest administrators to cause a denial of service (CPU consumption and possibly reboot) via crafted memory contents that triggers a "time-consuming linear scan," related to Populate-on-Demand.
CVE-2015-4103 1 Xen 1 Xen 2025-04-12 N/A
Xen 3.3.x through 4.5.x does not properly restrict write access to the host MSI message data field, which allows local x86 HVM guest administrators to cause a denial of service (host interrupt handling confusion) via vectors related to qemu and accessing spanning multiple fields.
CVE-2015-3456 3 Qemu, Redhat, Xen 7 Qemu, Enterprise Linux, Enterprise Virtualization and 4 more 2025-04-12 N/A
The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM.
CVE-2015-3340 5 Debian, Fedoraproject, Opensuse and 2 more 9 Debian Linux, Fedora, Opensuse and 6 more 2025-04-12 N/A
Xen 4.2.x through 4.5.x does not initialize certain fields, which allows certain remote service domains to obtain sensitive information from memory via a (1) XEN_DOMCTL_gettscinfo or (2) XEN_SYSCTL_getdomaininfolist request.
CVE-2015-3259 1 Xen 1 Xen 2025-04-12 N/A
Stack-based buffer overflow in the xl command line utility in Xen 4.1.x through 4.5.x allows local guest administrators to gain privileges via a long configuration argument.
CVE-2015-2756 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2025-04-12 N/A
QEMU, as used in Xen 3.3.x through 4.5.x, does not properly restrict access to PCI command registers, which might allow local HVM guest users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response.
CVE-2016-7777 1 Xen 1 Xen 2025-04-12 N/A
Xen 4.7.x and earlier does not properly honor CR0.TS and CR0.EM, which allows local x86 HVM guest OS users to read or modify FPU, MMX, or XMM register state information belonging to arbitrary tasks on the guest by modifying an instruction while the hypervisor is preparing to emulate it.
CVE-2015-2752 2 Fedoraproject, Xen 2 Fedora, Xen 2025-04-12 N/A
The XEN_DOMCTL_memory_mapping hypercall in Xen 3.2.x through 4.5.x, when using a PCI passthrough device, is not preemptible, which allows local x86 HVM domain users to cause a denial of service (host CPU consumption) via a crafted request to the device model (qemu-dm).
CVE-2015-8550 2 Novell, Xen 2 Suse Linux Enterprise Real Time Extension, Xen 2025-04-12 N/A
Xen, when used on a system providing PV backends, allows local guest OS administrators to cause a denial of service (host OS crash) or gain privileges by writing to memory shared between the frontend and backend, aka a double fetch vulnerability.
CVE-2015-2751 2 Fedoraproject, Xen 2 Fedora, Xen 2025-04-12 N/A
Xen 4.3.x, 4.4.x, and 4.5.x, when using toolstack disaggregation, allows remote domains with partial management control to cause a denial of service (host lock) via unspecified domctl operations.
CVE-2015-5165 7 Arista, Debian, Fedoraproject and 4 more 25 Eos, Debian Linux, Fedora and 22 more 2025-04-12 N/A
The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors.
CVE-2015-8554 1 Xen 1 Xen 2025-04-12 N/A
Buffer overflow in hw/pt-msi.c in Xen 4.6.x and earlier, when using the qemu-xen-traditional (aka qemu-dm) device model, allows local x86 HVM guest administrators to gain privileges by leveraging a system with access to a passed-through MSI-X capable physical PCI device and MSI-X table entries, related to a "write path."
CVE-2015-8555 2 Citrix, Xen 2 Xenserver, Xen 2025-04-12 N/A
Xen 4.6.x, 4.5.x, 4.4.x, 4.3.x, and earlier do not initialize x86 FPU stack and XMM registers when XSAVE/XRSTOR are not used to manage guest extended register state, which allows local guest domains to obtain sensitive information from other domains via unspecified vectors.
CVE-2015-2152 2 Fedoraproject, Xen 2 Fedora, Xen 2025-04-12 N/A
Xen 4.5.x and earlier enables certain default backends when emulating a VGA device for an x86 HVM guest qemu even when the configuration disables them, which allows local guest users to obtain access to the VGA console by (1) setting the DISPLAY environment variable, when compiled with SDL support, or connecting to the VNC server on (2) ::1 or (3) 127.0.0.1, when not compiled with SDL support.
CVE-2015-2150 3 Linux, Ubuntu, Xen 3 Linux Kernel, Ubuntu, Xen 2025-04-12 N/A
Xen 3.3.x through 4.5.x and the Linux kernel through 3.19.1 do not properly restrict access to PCI command registers, which might allow local guest OS users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response.
