| CVE-2016-7154 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Use-after-free vulnerability in the FIFO event channel code in Xen 4.4.x allows local guest OS administrators to cause a denial of service (host crash) and possibly execute arbitrary code or obtain sensitive information via an invalid guest frame number. | ||||
| CVE-2016-5242 | 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-2014-7156 | 1 Xen | 1 Xen | 2025-04-12 | 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-2014-7188 | 1 Xen | 1 Xen | 2025-04-12 | 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-2014-7154 | 4 Debian, Fedoraproject, Opensuse and 1 more | 4 Debian Linux, Fedora, Opensuse and 1 more | 2025-04-12 | N/A |
| Race condition in HVMOP_track_dirty_vram in Xen 4.0.0 through 4.4.x does not ensure possession of the guarding lock for dirty video RAM tracking, which allows certain local guest domains to cause a denial of service via unspecified vectors. | ||||
| 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-2016-2270 | 4 Debian, Fedoraproject, Oracle and 1 more | 4 Debian Linux, Fedora, Vm Server and 1 more | 2025-04-12 | N/A |
| Xen 4.6.x and earlier allows local guest administrators to cause a denial of service (host reboot) via vectors related to multiple mappings of MMIO pages with different cachability settings. | ||||
| CVE-2015-6654 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The xenmem_add_to_physmap_one function in arch/arm/mm.c in Xen 4.5.x, 4.4.x, and earlier does not limit the number of printk console messages when reporting a failure to retrieve a reference on a foreign page, which allows remote domains to cause a denial of service by leveraging permissions to map the memory of a foreign guest. | ||||
| CVE-2014-9065 | 2 Opensuse, Xen | 2 Opensuse, Xen | 2025-04-12 | N/A |
| common/spinlock.c in Xen 4.4.x and earlier 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 to CVE-2014-9066. | ||||
| CVE-2015-5154 | 5 Fedoraproject, Qemu, Redhat and 2 more | 10 Fedora, Qemu, Enterprise Linux and 7 more | 2025-04-12 | N/A |

| The vgic_v2_to_sgi function in arch/arm/vgic-v2.c in Xen 4.5.x, when running on ARM hardware with general interrupt controller (GIC) version 2, allows local guest users to cause a denial of service (host crash) by writing an invalid value to the GICD.SGIR register. | ||||
| CVE-2015-7311 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| libxl in Xen 4.1.x through 4.6.x does not properly handle the readonly flag on disks when using the qemu-xen device model, which allows local guest users to write to a read-only disk image. | ||||
| CVE-2015-7814 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| 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. | ||||
