| CVE-2019-18422 | Hig | 0.57 | 8.8 | 0.02 | Oct 31, 2019 | An issue was discovered in Xen through 4.12.x allowing ARM guest OS users to cause a denial of service or gain privileges by leveraging the erroneous enabling of interrupts. Interrupts are unconditionally unmasked in exception handlers. When an exception occurs on an ARM system… | ||
| CVE-2018-19966 | Hig | 0.57 | 8.8 | 0.00 | Dec 8, 2018 | An issue was discovered in Xen through 4.11.x allowing x86 PV guest OS users to cause a denial of service (host OS crash) or possibly gain host OS privileges because of an interpretation conflict for a union data structure associated with shadow paging. NOTE: this issue exists… | ||
| 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-2020-25599 | Hig | 0.46 | 7.0 | 0.00 | Sep 23, 2020 | An issue was discovered in Xen through 4.14.x. There are evtchn_reset() race conditions. Uses of EVTCHNOP_reset (potentially by a guest on itself) or XEN_DOMCTL_soft_reset (by itself covered by XSA-77) can lead to the violation of various internal assumptions. This may lead to… | ||
| 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-2020-11742 | Med | 0.36 | 5.5 | 0.00 | Apr 14, 2020 | An issue was discovered in Xen through 4.13.x, allowing guest OS users to cause a denial of service because of bad continuation handling in GNTTABOP_copy. Grant table operations are expected to return 0 for success, and a negative number for errors. The fix for CVE-2017-12135… | ||
| CVE-2020-27674 | Med | 0.34 | 5.3 | 0.00 | Oct 22, 2020 | An issue was discovered in Xen through 4.14.x allowing x86 PV guest OS users to gain guest OS privileges by modifying kernel memory contents, because invalidation of TLB entries is mishandled during use of an INVLPG-like attack technique. |
