| CVE-2017-15594 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| An issue was discovered in Xen through 4.9.x allowing x86 SVM PV guest OS users to cause a denial of service (hypervisor crash) or gain privileges because IDT settings are mishandled during CPU hotplugging. | ||||
| CVE-2017-10919 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| Xen through 4.8.x mishandles virtual interrupt injection, which allows guest OS users to cause a denial of service (hypervisor crash), aka XSA-223. | ||||
| CVE-2017-17044 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| An issue was discovered in Xen through 4.9.x allowing HVM guest OS users to cause a denial of service (infinite loop and host OS hang) by leveraging the mishandling of Populate on Demand (PoD) errors. | ||||
| CVE-2017-7228 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| An issue (known as XSA-212) was discovered in Xen, with fixes available for 4.8.x, 4.7.x, 4.6.x, 4.5.x, and 4.4.x. The earlier XSA-29 fix introduced an insufficient check on XENMEM_exchange input, allowing the caller to drive hypervisor memory accesses outside of the guest provided input/output arrays. | ||||
| CVE-2023-34321 | 1 Xen | 1 Xen | 2025-04-17 | 3.3 Low |
| Arm provides multiple helpers to clean & invalidate the cache for a given region. This is, for instance, used when allocating guest memory to ensure any writes (such as the ones during scrubbing) have reached memory before handing over the page to a guest. Unfortunately, the arithmetics in the helpers can overflow and would then result to skip the cache cleaning/invalidation. Therefore there is no guarantee when all the writes will reach the memory. | ||||
| CVE-2015-2044 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The emulation routines for unspecified X86 devices in Xen 3.2.x through 4.5.x does not properly initialize data, which allow local HVM guest users to obtain sensitive information via vectors involving an unsupported access size. | ||||
| CVE-2015-0268 | 1 Xen | 1 Xen | 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-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-2014-9030 | 3 Debian, Opensuse, Xen | 3 Debian Linux, Opensuse, Xen | 2025-04-12 | 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-2014-8867 | 4 Debian, Opensuse, Redhat and 1 more | 5 Debian Linux, Opensuse, Enterprise Linux and 2 more | 2025-04-12 | 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-2015-7812 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The hypercall_create_continuation function in arch/arm/domain.c in Xen 4.4.x through 4.6.x allows local guest users to cause a denial of service (host crash) via a preemptible hypercall to the multicall interface. | ||||
| 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-2014-8594 | 3 Debian, Opensuse, Xen | 3 Debian Linux, Opensuse, Xen | 2025-04-12 | N/A |
| The do_mmu_update function in arch/x86/mm.c in Xen 4.x through 4.4.x does not properly restrict updates to only PV page tables, which allows remote PV guests to cause a denial of service (NULL pointer dereference) by leveraging hardware emulation services for HVM guests using Hardware Assisted Paging (HAP). | ||||
| 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. | ||||
| 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-2014-7156 | 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-2016-4962 | 2 Oracle, Xen | 2 Vm Server, Xen | 2025-04-12 | N/A |
| The libxl device-handling in Xen 4.6.x and earlier allows local OS guest administrators to cause a denial of service (resource consumption or management facility confusion) or gain host OS privileges by manipulating information in guest controlled areas of xenstore. | ||||
