Race condition in the relinquish_memory function in arch/arm/domain.c in Xen 4.6.x and earlier allows local domains with partial management control to cause a denial of service (host crash) via vectors involving the destruction of a domain and using XENMEM_decrease_reservation to reduce the memory of the domain.
CVE-2016-3960 3 Fedoraproject, Oracle, Xen 3 Fedora, Vm Server, Xen 2025-04-12 7.2 HIGH 8.8 HIGH
Integer overflow in the x86 shadow pagetable code in Xen allows local guest OS users to cause a denial of service (host crash) or possibly gain privileges by shadowing a superpage mapping.
CVE-2016-4480 2 Oracle, Xen 2 Vm Server, Xen 2025-04-12 7.2 HIGH 8.4 HIGH
The guest_walk_tables function in arch/x86/mm/guest_walk.c in Xen 4.6.x and earlier does not properly handle the Page Size (PS) page table entry bit at the L4 and L3 page table levels, which might allow local guest OS users to gain privileges via a crafted mapping of memory.
CVE-2014-3717 1 Xen 1 Xen 2025-04-12 3.3 LOW 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.

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-2015-3340 5 Debian, Fedoraproject, Opensuse and 2 more 9 Debian Linux, Fedora, Opensuse and 6 more 2025-04-12 2.9 LOW 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-2014-7156 1 Xen 1 Xen 2025-04-12 3.3 LOW N/A
The x86_emulate function in arch/x86/x86_emulate/x86_emulate.c in Xen 3.3.x through 4.4.x does not check the supervisor mode permissions for instructions that generate software interrupts, which allows local HVM guest users to cause a denial of service (guest crash) via unspecified vectors.
CVE-2015-2152 2 Fedoraproject, Xen 2 Fedora, Xen 2025-04-12 1.9 LOW 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-2014-8867 4 Debian, Opensuse, Redhat and 1 more 5 Debian Linux, Opensuse, Enterprise Linux and 2 more 2025-04-12 4.9 MEDIUM N/A
The acceleration support for the "REP MOVS" instruction in Xen 4.4.x, 3.2.x, and earlier lacks properly bounds checking for memory mapped I/O (MMIO) emulated in the hypervisor, which allows local HVM guests to cause a denial of service (host crash) via unspecified vectors.
CVE-2014-5149 2 Opensuse, Xen 2 Opensuse, Xen 2025-04-12 4.7 MEDIUM N/A
Certain MMU virtualization operations in Xen 4.2.x through 4.4.x, when using shadow pagetables, are not preemptible, which allows local HVM guest to cause a denial of service (vcpu consumption) by invoking these operations, which process every page assigned to a guest, a different vulnerability than CVE-2014-5146.
CVE-2014-7188 1 Xen 1 Xen 2025-04-12 8.3 HIGH N/A
The hvm_msr_read_intercept function in arch/x86/hvm/hvm.c in Xen 4.1 through 4.4.x uses an improper MSR range for x2APIC emulation, which allows local HVM guests to cause a denial of service (host crash) or read data from the hypervisor or other guests via unspecified vectors.
CVE-2015-2045 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2025-04-12 2.1 LOW N/A
The HYPERVISOR_xen_version hypercall in Xen 3.2.x through 4.5.x does not properly initialize data structures, which allows local guest users to obtain sensitive information via unspecified vectors.
CVE-2014-9030 3 Debian, Opensuse, Xen 3 Debian Linux, Opensuse, Xen 2025-04-12 7.1 HIGH N/A
The do_mmu_update function in arch/x86/mm.c in Xen 3.2.x through 4.4.x does not properly manage page references, which allows remote domains to cause a denial of service by leveraging control over an HVM guest and a crafted MMU_MACHPHYS_UPDATE.
CVE-2014-3715 1 Xen 1 Xen 2025-04-12 3.3 LOW 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-2015-0777 2 Linux, Xen 2 Linux Kernel, Xen 2025-04-12 2.1 LOW N/A
drivers/xen/usbback/usbback.c in linux-2.6.18-xen-3.4.0 (aka the Xen 3.4.x support patches for the Linux kernel 2.6.18), as used in the Linux kernel 2.6.x and 3.x in SUSE Linux distributions, allows guest OS users to obtain sensitive information from uninitialized locations in host OS kernel memory via unspecified vectors.
CVE-2014-8866 3 Debian, Opensuse, Xen 3 Debian Linux, Opensuse, Xen 2025-04-12 4.7 MEDIUM N/A
The compatibility mode hypercall argument translation in Xen 3.3.x through 4.4.x, when running on a 64-bit hypervisor, allows local 32-bit HVM guests to cause a denial of service (host crash) via vectors involving altering the high halves of registers while in 64-bit mode.
CVE-2015-7813 1 Xen 1 Xen 2025-04-12 2.1 LOW N/A
Xen 4.4.x, 4.5.x, and 4.6.x does not limit the number of printk console messages when reporting unimplemented hypercalls, which allows local guests to cause a denial of service via a sequence of (1) HYPERVISOR_physdev_op hypercalls, which are not properly handled in the do_physdev_op function in arch/arm/physdev.c, or (2) HYPERVISOR_hvm_op hypercalls, which are not properly handled in the do_hvm_op function in arch/arm/hvm.c.
CVE-2014-4021 1 Xen 1 Xen 2025-04-12 2.7 LOW N/A
Xen 3.2.x through 4.4.x does not properly clean memory pages recovered from guests, which allows local guest OS users to obtain sensitive information via unspecified vectors.

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-2014-9066 2 Opensuse, Xen 2 Opensuse, Xen 2025-04-12 4.7 MEDIUM N/A
Xen 4.4.x and earlier, when using a large number of VCPUs, does not properly handle read and write locks, which allows local x86 guest users to cause a denial of service (write denial or NMI watchdog timeout and host crash) via a large number of read requests, a different vulnerability than CVE-2014-9065.
