| Xen 4.4.x, when running a 64-bit kernel on an ARM system, does not properly handle traps from the guest domain that use a different address width, which allows local guest users to cause a denial of service (host crash) via a crafted 32-bit process. | |||||
| CVE-2015-2150 | 3 Linux, Ubuntu, Xen | 3 Linux Kernel, Ubuntu, Xen | 2025-04-12 | 4.9 MEDIUM | 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. | |||||
| CVE-2015-7814 | 1 Xen | 1 Xen | 2025-04-12 | 4.7 MEDIUM | 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-2014-5148 | 1 Xen | 1 Xen | 2025-04-12 | 4.6 MEDIUM | N/A |
| Xen 4.4.x, when running on an ARM system and "handling an unknown system register access from 64-bit userspace," returns to an instruction of the trap handler for kernel space faults instead of an instruction that is associated with faults in 64-bit userspace, which allows local guest users to cause a denial of service (crash) and possibly gain privileges via a crafted process. | |||||
| 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. | |||||
| CVE-2015-8339 | 1 Xen | 1 Xen | 2025-04-12 | 4.7 MEDIUM | N/A |
| The memory_exchange function in common/memory.c in Xen 3.2.x through 4.6.x does not properly hand back pages to a domain, which might allow guest OS administrators to cause a denial of service (host crash) via unspecified vectors related to domain teardown. | |||||

| 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. | |||||

| 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-2015-4105 | 1 Xen | 1 Xen | 2025-04-12 | 4.9 MEDIUM | N/A |
