| CVE-2017-10922 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| The grant-table feature in Xen through 4.8.x mishandles MMIO region grant references, which allows guest OS users to cause a denial of service (loss of grant trackability), aka XSA-224 bug 3. | ||||
| 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-2017-17563 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| 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-2017-15595 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| 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-2016-9382 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
| Xen 4.0.x through 4.7.x mishandle x86 task switches to VM86 mode, which allows local 32-bit x86 HVM guest OS users to gain privileges or cause a denial of service (guest OS crash) by leveraging a guest operating system that uses hardware task switching and allows a new task to start in VM86 mode. | ||||
| CVE-2016-9379 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
| The pygrub boot loader emulator in Xen, when S-expression output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via string quotes and S-expressions in the bootloader configuration file. | ||||
| CVE-2016-9385 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
| The x86 segment base write emulation functionality in Xen 4.4.x through 4.7.x allows local x86 PV guest OS administrators to cause a denial of service (host crash) by leveraging lack of canonical address checks. | ||||
| CVE-2017-15593 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to cause a denial of service (memory leak) because reference counts are mishandled. | ||||
| CVE-2017-15592 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| 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-2017-12855 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| 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-2017-10917 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| Xen through 4.8.x does not validate the port numbers of polled event channel ports, which allows guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) or possibly obtain sensitive information, aka XSA-221. | ||||
| CVE-2017-12135 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2025-04-20 | N/A |
| Xen allows local OS guest users to cause a denial of service (crash) or possibly obtain sensitive information or gain privileges via vectors involving transitive grants. | ||||
| 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-2016-10025 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
| VMFUNC emulation in Xen 4.6.x through 4.8.x on x86 systems using AMD virtualization extensions (aka SVM) allows local HVM guest OS users to cause a denial of service (hypervisor crash) by leveraging a missing NULL pointer check. | ||||
| CVE-2017-10912 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| Xen through 4.8.x mishandles page transfer, which allows guest OS users to obtain privileged host OS access, aka XSA-217. | ||||
| CVE-2017-10920 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| The grant-table feature in Xen through 4.8.x mishandles a GNTMAP_device_map and GNTMAP_host_map mapping, when followed by only a GNTMAP_host_map unmapping, 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 1. | ||||
| CVE-2017-17565 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| 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-2017-14431 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| 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-2016-9818 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| 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 HYP. | ||||
| CVE-2016-9817 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| Xen through 4.7.x allows local ARM guest OS users to cause a denial of service (host crash) via vectors involving a (1) data or (2) prefetch abort with the ESR_EL2.EA bit set. | ||||
