The fpu_fxrstor function in arch/x86/i387.c in Xen 4.x does not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors, which allows local guest OS users to obtain sensitive register content information from another guest by leveraging pending exception and mask bits. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-2076. | ||||
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-2016-3158 | 3 Fedoraproject, Oracle, Xen | 3 Fedora, Vm Server, Xen | 2025-04-12 | N/A |
The xrstor function in arch/x86/xstate.c in Xen 4.x does not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors, which allows local guest OS users to obtain sensitive register content information from another guest by leveraging pending exception and mask bits. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-2076. | ||||
CVE-2016-2271 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
VMX in Xen 4.6.x and earlier, when using an Intel or Cyrix CPU, allows local HVM guest users to cause a denial of service (guest crash) via vectors related to a non-canonical RIP. | ||||
CVE-2016-1571 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-12 | N/A |
The paging_invlpg function in include/asm-x86/paging.h in Xen 3.3.x through 4.6.x, when using shadow mode paging or nested virtualization is enabled, allows local HVM guest users to cause a denial of service (host crash) via a non-canonical guest address in an INVVPID instruction, which triggers a hypervisor bug check. | ||||
CVE-2015-8554 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
Buffer overflow in hw/pt-msi.c in Xen 4.6.x and earlier, when using the qemu-xen-traditional (aka qemu-dm) device model, allows local x86 HVM guest administrators to gain privileges by leveraging a system with access to a passed-through MSI-X capable physical PCI device and MSI-X table entries, related to a "write path." | ||||
CVE-2015-8553 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-12 | N/A |
Xen allows guest OS users to obtain sensitive information from uninitialized locations in host OS kernel memory by not enabling memory and I/O decoding control bits. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-0777. | ||||
CVE-2015-8552 | 4 Canonical, Debian, Novell and 1 more | 5 Ubuntu Linux, Debian Linux, Suse Linux Enterprise Debuginfo and 2 more | 2025-04-12 | N/A |
The PCI backend driver in Xen, when running on an x86 system and using Linux 3.1.x through 4.3.x as the driver domain, allows local guest administrators to generate a continuous stream of WARN messages and cause a denial of service (disk consumption) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and XEN_PCI_OP_enable_msi operations, aka "Linux pciback missing sanity checks." | ||||
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-2016-4480 | 2 Oracle, Xen | 2 Vm Server, Xen | 2025-04-12 | N/A |
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-2015-8341 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
The libxl toolstack library in Xen 4.1.x through 4.6.x does not properly release mappings of files used as kernels and initial ramdisks when managing multiple domains in the same process, which allows attackers to cause a denial of service (memory and disk consumption) by starting domains. | ||||

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. | ||||
CVE-2016-7093 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
Xen 4.5.3, 4.6.3, and 4.7.x allow local HVM guest OS administrators to overwrite hypervisor memory and consequently gain host OS privileges by leveraging mishandling of instruction pointer truncation during emulation. | ||||
CVE-2015-7971 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
Xen 3.2.x through 4.6.x does not limit the number of printk console messages when logging certain pmu and profiling hypercalls, which allows local guests to cause a denial of service via a sequence of crafted (1) HYPERCALL_xenoprof_op hypercalls, which are not properly handled in the do_xenoprof_op function in common/xenoprof.c, or (2) HYPERVISOR_xenpmu_op hypercalls, which are not properly handled in the do_xenpmu_op function in arch/x86/cpu/vpmu.c. | ||||
