| Xen through 4.8.x mishandles the "contains segment descriptors" property during GNTTABOP_transfer (aka guest transfer) operations, which might allow PV guest OS users to execute arbitrary code on the host OS, aka XSA-214. | |||||

| CVE-2016-9383 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | 7.2 HIGH | 8.8 HIGH |
| Xen, when running on a 64-bit hypervisor, allows local x86 guest OS users to modify arbitrary memory and consequently obtain sensitive information, cause a denial of service (host crash), or execute arbitrary code on the host by leveraging broken emulation of bit test instructions. | |||||
| CVE-2017-10916 | 1 Xen | 1 Xen | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| The vCPU context-switch implementation in Xen through 4.8.x improperly interacts with the Memory Protection Extensions (MPX) and Protection Key (PKU) features, which makes it easier for guest OS users to defeat ASLR and other protection mechanisms, aka XSA-220. | |||||
| CVE-2017-17045 | 1 Xen | 1 Xen | 2025-04-20 | 7.2 HIGH | 8.8 HIGH |
| An issue was discovered in Xen through 4.9.x allowing HVM guest OS users to gain privileges on the host OS, obtain sensitive information, or cause a denial of service (BUG and host OS crash) by leveraging the mishandling of Populate on Demand (PoD) Physical-to-Machine (P2M) errors. | |||||
| CVE-2017-14431 | 1 Xen | 1 Xen | 2025-04-20 | 4.9 MEDIUM | 5.5 MEDIUM |
| Memory leak in Xen 3.3 through 4.8.x allows guest OS users to cause a denial of service (ARM or x86 AMD host OS memory consumption) by continually rebooting, because certain cleanup is skipped if no pass-through device was ever assigned, aka XSA-207. | |||||
| CVE-2016-10024 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | 4.9 MEDIUM | 6.0 MEDIUM |
| Xen through 4.8.x allows local x86 PV guest OS kernel administrators to cause a denial of service (host hang or crash) by modifying the instruction stream asynchronously while performing certain kernel operations. | |||||
| CVE-2017-17563 | 1 Xen | 1 Xen | 2025-04-20 | 6.9 MEDIUM | 7.8 HIGH |
| An issue was discovered in Xen through 4.9.x allowing guest OS users to cause a denial of service (host OS crash) or gain host OS privileges by leveraging an incorrect mask for reference-count overflow checking in shadow mode. | |||||
| CVE-2017-14318 | 1 Xen | 1 Xen | 2025-04-20 | 4.9 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Xen 4.5.x through 4.9.x. The function `__gnttab_cache_flush` handles GNTTABOP_cache_flush grant table operations. It checks to see if the calling domain is the owner of the page that is to be operated on. If it is not, the owner's grant table is checked to see if a grant mapping to the calling domain exists for the page in question. However, the function does not check to see if the owning domain actually has a grant table or not. Some special domains, such as `DOMID_XEN`, `DOMID_IO` and `DOMID_COW` are created without grant tables. Hence, if __gnttab_cache_flush operates on a page owned by these special domains, it will attempt to dereference a NULL pointer in the domain struct. | |||||
| CVE-2017-15595 | 1 Xen | 1 Xen | 2025-04-20 | 7.2 HIGH | 8.8 HIGH |
| An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to cause a denial of service (unbounded recursion, stack consumption, and hypervisor crash) or possibly gain privileges via crafted page-table stacking. | |||||
| CVE-2023-34321 | 1 Xen | 1 Xen | 2025-04-17 | N/A | 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-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-2016-3157 | 2 Canonical, Xen | 2 Ubuntu Linux, Xen | 2025-04-12 | 7.2 HIGH | 7.8 HIGH |
| The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel does not properly context-switch IOPL on 64-bit PV Xen guests, which allows local guest OS users to gain privileges, cause a denial of service (guest OS crash), or obtain sensitive information by leveraging I/O port access. | |||||
| CVE-2015-7835 | 1 Xen | 1 Xen | 2025-04-12 | 7.2 HIGH | N/A |
| The mod_l2_entry function in arch/x86/mm.c in Xen 3.4 through 4.6.x does not properly validate level 2 page table entries, which allows local PV guest administrators to gain privileges via a crafted superpage mapping. | |||||
| CVE-2014-3968 | 2 Opensuse, Xen | 2 Opensuse, Xen | 2025-04-12 | 5.5 MEDIUM | N/A |
| The HVMOP_inject_msi function in Xen 4.2.x, 4.3.x, and 4.4.x allows local guest HVM administrators to cause a denial of service (host crash) via a large number of crafted requests, which trigger an error messages to be logged. | |||||
| CVE-2016-7154 | 1 Xen | 1 Xen | 2025-04-12 | 7.2 HIGH | 6.7 MEDIUM |
| 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-2014-3672 | 2 Redhat, Xen | 2 Libvirt, Xen | 2025-04-12 | 2.1 LOW | 6.5 MEDIUM |
| The qemu implementation in libvirt before 1.3.0 and Xen allows local guest OS users to cause a denial of service (host disk consumption) by writing to stdout or stderr. | |||||
| 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-2016-3158 | 3 Fedoraproject, Oracle, Xen | 3 Fedora, Vm Server, Xen | 2025-04-12 | 1.7 LOW | 3.8 LOW |
| 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-2014-7155 | 4 Debian, Fedoraproject, Opensuse and 1 more | 4 Debian Linux, Fedora, Opensuse and 1 more | 2025-04-12 | 5.8 MEDIUM | N/A |
| The x86_emulate function in arch/x86/x86_emulate/x86_emulate.c in Xen 4.4.x and earlier does not properly check supervisor mode permissions, which allows local HVM users to cause a denial of service (guest crash) or gain guest kernel mode privileges via vectors involving an (1) HLT, (2) LGDT, (3) LIDT, or (4) LMSW instruction. | |||||
