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-2014-3717 1 Xen 1 Xen 2025-04-12 N/A
Xen 4.4.x does not properly validate the load address for 64-bit ARM guest kernels, which allows local users to read system memory or cause a denial of service (crash) via a crafted kernel, which triggers a buffer overflow.
CVE-2014-3715 1 Xen 1 Xen 2025-04-12 N/A
Buffer overflow in Xen 4.4.x allows local users to read system memory or cause a denial of service (crash) via a crafted 32-bit guest kernel, related to searching for an appended DTB.
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-2014-3672 2 Redhat, Xen 2 Libvirt, Xen 2025-04-12 N/A
The qemu implementation in libvirt before 1.3.0 and Xen allows local guest OS users to cause a denial of service (host disk consumption) by writing to stdout or stderr.
CVE-2014-3714 1 Xen 1 Xen 2025-04-12 N/A
The ARM image loading functionality in Xen 4.4.x does not properly validate kernel length, which allows local users to read system memory or cause a denial of service (crash) via a crafted 32-bit ARM guest kernel in an image, which triggers a buffer overflow.
CVE-2016-7092 1 Xen 1 Xen 2025-04-12 N/A
The get_page_from_l3e function in arch/x86/mm.c in Xen allows local 32-bit PV guest OS administrators to gain host OS privileges via vectors related to L3 recursive pagetables.
CVE-2016-6258 2 Citrix, Xen 2 Xenserver, Xen 2025-04-12 N/A
The PV pagetable code in arch/x86/mm.c in Xen 4.7.x and earlier allows local 32-bit PV guest OS administrators to gain host OS privileges by leveraging fast-paths for updating pagetable entries.
CVE-2014-2986 1 Xen 1 Xen 2025-04-12 N/A
The vgic_distr_mmio_write function in the virtual guest interrupt controller (GIC) distributor (arch/arm/vgic.c) in Xen 4.4.x, when running on an ARM system, allows local guest users to cause a denial of service (NULL pointer dereference and host crash) via unspecified vectors.
CVE-2011-3346 3 Qemu, Redhat, Xen 3 Qemu, Enterprise Linux, Xen 2025-04-12 N/A
Buffer overflow in hw/scsi-disk.c in the SCSI subsystem in QEMU before 0.15.2, as used by Xen, might allow local guest users with permission to access the CD-ROM to cause a denial of service (guest crash) via a crafted SAI READ CAPACITY SCSI command. NOTE: this is only a vulnerability when root has manually modified certain permissions or ACLs.
CVE-2014-8595 3 Debian, Opensuse, Xen 3 Debian Linux, Opensuse, Xen 2025-04-12 N/A
arch/x86/x86_emulate/x86_emulate.c in Xen 3.2.1 through 4.4.x does not properly check privileges, which allows local HVM guest users to gain privileges or cause a denial of service (crash) via a crafted (1) CALL, (2) JMP, (3) RETF, (4) LCALL, (5) LJMP, or (6) LRET far branch instruction.
CVE-2014-3968 2 Opensuse, Xen 2 Opensuse, Xen 2025-04-12 N/A
The HVMOP_inject_msi function in Xen 4.2.x, 4.3.x, and 4.4.x allows local guest HVM administrators to cause a denial of service (host crash) via a large number of crafted requests, which trigger an error messages to be logged.
CVE-2014-1892 1 Xen 1 Xen 2025-04-12 N/A
Xen 3.3 through 4.1, when XSM is enabled, allows local users to cause a denial of service via vectors related to a "large memory allocation," a different vulnerability than CVE-2014-1891, CVE-2014-1893, and CVE-2014-1894.
CVE-2016-4963 1 Xen 1 Xen 2025-04-12 N/A

The p2m_teardown function in arch/arm/p2m.c in Xen 4.4.x through 4.6.x allows local guest OS users with access to the driver domain to cause a denial of service (NULL pointer dereference and host OS crash) by creating concurrent domains and holding references to them, related to VMID exhaustion.
CVE-2015-5307 6 Canonical, Debian, Linux and 3 more 9 Ubuntu Linux, Debian Linux, Linux Kernel and 6 more 2025-04-12 N/A
