| CVE-2017-10919 | 1 Xen | 1 Xen | 2025-04-20 | 5.0 MEDIUM | 6.5 MEDIUM |
| 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-2017-12855 | 1 Xen | 1 Xen | 2025-04-20 | 2.1 LOW | 6.5 MEDIUM |
| Xen maintains the _GTF_{read,writ}ing bits as appropriate, to inform the guest that a grant is in use. A guest is expected not to modify the grant details while it is in use, whereas the guest is free to modify/reuse the grant entry when it is not in use. Under some circumstances, Xen will clear the status bits too early, incorrectly informing the guest that the grant is no longer in use. A guest may prematurely believe that a granted frame is safely private again, and reuse it in a way which contains sensitive information, while the domain on the far end of the grant is still using the grant. Xen 4.9, 4.8, 4.7, 4.6, and 4.5 are affected. | |||||
| 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-2016-9379 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | 4.6 MEDIUM | 7.9 HIGH |

| CVE-2017-15589 | 1 Xen | 1 Xen | 2025-04-20 | 2.1 LOW | 6.5 MEDIUM |
| An issue was discovered in Xen through 4.9.x allowing x86 HVM guest OS users to obtain sensitive information from the host OS (or an arbitrary guest OS) because intercepted I/O operations can cause a write of data from uninitialized hypervisor stack memory. | |||||
| CVE-2017-17044 | 1 Xen | 1 Xen | 2025-04-20 | 4.9 MEDIUM | 6.5 MEDIUM |
| 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-2016-9377 | 1 Xen | 1 Xen | 2025-04-20 | 2.1 LOW | 5.5 MEDIUM |
| Xen 4.5.x through 4.7.x on AMD systems without the NRip feature, when emulating instructions that generate software interrupts, allows local HVM guest OS users to cause a denial of service (guest crash) by leveraging IDT entry miscalculation. | |||||
| CVE-2016-9384 | 1 Xen | 1 Xen | 2025-04-20 | 2.1 LOW | 6.5 MEDIUM |
| Xen 4.7 allows local guest OS users to obtain sensitive host information by loading a 32-bit ELF symbol table. | |||||
| CVE-2017-10915 | 1 Xen | 1 Xen | 2025-04-20 | 6.8 MEDIUM | 9.0 CRITICAL |
| The shadow-paging feature in Xen through 4.8.x mismanages page references and consequently introduces a race condition, which allows guest OS users to obtain Xen privileges, aka XSA-219. | |||||
| CVE-2017-15596 | 1 Xen | 1 Xen | 2025-04-20 | 4.9 MEDIUM | 6.0 MEDIUM |
| An issue was discovered in Xen 4.4.x through 4.9.x allowing ARM guest OS users to cause a denial of service (prevent physical CPU usage) because of lock mishandling upon detection of an add-to-physmap error. | |||||
| CVE-2016-9816 | 1 Xen | 1 Xen | 2025-04-20 | 4.9 MEDIUM | 6.5 MEDIUM |
| Xen through 4.7.x allows local ARM guest OS users to cause a denial of service (host crash) via vectors involving an asynchronous abort while at EL2. | |||||
| CVE-2017-15592 | 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 HVM guest OS users to cause a denial of service (hypervisor crash) or possibly gain privileges because self-linear shadow mappings are mishandled for translated guests. | |||||
| CVE-2017-10921 | 1 Xen | 1 Xen | 2025-04-20 | 10.0 HIGH | 10.0 CRITICAL |
| The grant-table feature in Xen through 4.8.x does not ensure sufficient type counts for a GNTMAP_device_map and GNTMAP_host_map mapping, which allows guest OS users to cause a denial of service (count mismanagement and memory corruption) or obtain privileged host OS access, aka XSA-224 bug 2. | |||||
| CVE-2017-14319 | 1 Xen | 1 Xen | 2025-04-20 | 7.2 HIGH | 8.8 HIGH |
| A grant unmapping issue was discovered in Xen through 4.9.x. When removing or replacing a grant mapping, the x86 PV specific path needs to make sure page table entries remain in sync with other accounting done. Although the identity of the page frame was validated correctly, neither the presence of the mapping nor page writability were taken into account. | |||||
| CVE-2016-9380 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | 4.6 MEDIUM | 7.5 HIGH |
| The pygrub boot loader emulator in Xen, when nul-delimited output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via NUL bytes in the bootloader configuration file. | |||||
| CVE-2017-17046 | 1 Xen | 1 Xen | 2025-04-20 | 2.1 LOW | 6.5 MEDIUM |
| An issue was discovered in Xen through 4.9.x on the ARM platform allowing guest OS users to obtain sensitive information from DRAM after a reboot, because disjoint blocks, and physical addresses that do not start at zero, are mishandled. | |||||
| CVE-2017-12137 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2025-04-20 | 7.2 HIGH | 8.8 HIGH |
| arch/x86/mm.c in Xen allows local PV guest OS users to gain host OS privileges via vectors related to map_grant_ref. | |||||
| CVE-2017-17565 | 1 Xen | 1 Xen | 2025-04-20 | 4.7 MEDIUM | 5.6 MEDIUM |
| An issue was discovered in Xen through 4.9.x allowing PV guest OS users to cause a denial of service (host OS crash) if shadow mode and log-dirty mode are in place, because of an incorrect assertion related to M2P. | |||||
| 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-2017-14317 | 1 Xen | 1 Xen | 2025-04-20 | 4.7 MEDIUM | 5.6 MEDIUM |
| A domain cleanup issue was discovered in the C xenstore daemon (aka cxenstored) in Xen through 4.9.x. When shutting down a VM with a stubdomain, a race in cxenstored may cause a double-free. The xenstored daemon may crash, resulting in a DoS of any parts of the system relying on it (including domain creation / destruction, ballooning, device changes, etc.). | |||||
