| CVE-2017-15592 | Hig | 0.57 | 8.8 | 0.00 | Oct 18, 2017 | 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-2017-14316 | Hig | 0.57 | 8.8 | 0.00 | Sep 12, 2017 | A parameter verification issue was discovered in Xen through 4.9.x. The function `alloc_heap_pages` allows callers to specify the first NUMA node that should be used for allocations through the `memflags` parameter; the node is extracted using the `MEMF_get_node` macro. While… | ||

| CVE-2017-14318 | Med | 0.42 | 6.5 | 0.00 | Sep 12, 2017 | 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… | ||
| CVE-2017-12855 | Med | 0.42 | 6.5 | 0.00 | Aug 15, 2017 | 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… | ||

| CVE-2010-3699 | 0.00 | — | 0.01 | Dec 8, 2010 | The backend driver in Xen 3.x allows guest OS users to cause a denial of service via a kernel thread leak, which prevents the device and guest OS from being shut down or create a zombie domain, causes a hang in zenwatch, or prevents unspecified xm commands from working properly,… | |||
| CVE-2008-5716 | 0.00 | — | 0.00 | Dec 24, 2008 | xend in Xen 3.3.0 does not properly restrict a guest VM's write access within the /local/domain xenstore directory tree, which allows guest OS users to cause a denial of service and possibly have unspecified other impact by writing to (1) console/tty, (2) console/limit, or (3)… |
