| CVE-2018-19963 | Hig | 7.8 | < 4.15.1_01-1.2 | 4.15.1_01-1.2 | Dec 8, 2018 | An issue was discovered in Xen 4.11 allowing HVM guest OS users to cause a denial of service (host OS crash) or possibly gain host OS privileges because x86 IOREQ server resource accounting (for external emulators) was mishandled. | |
| CVE-2018-19961 | Hig | 7.8 | < 4.15.1_01-1.2 | 4.15.1_01-1.2 | Dec 8, 2018 | An issue was discovered in Xen through 4.11.x on AMD x86 platforms, possibly allowing guest OS users to gain host OS privileges because TLB flushes do not always occur after IOMMU mapping changes. | |
| CVE-2018-18883 | Hig | 8.8 | < 4.15.1_01-1.2 | 4.15.1_01-1.2 | Nov 1, 2018 | An issue was discovered in Xen 4.9.x through 4.11.x, on Intel x86 platforms, allowing x86 HVM and PVH guests to cause a host OS denial of service (NULL pointer dereference) or possibly have unspecified other impact because nested VT-x is not properly restricted. | |
| CVE-2018-15470 | Med | 6.5 | < 4.15.1_01-1.2 | 4.15.1_01-1.2 | Aug 17, 2018 | An issue was discovered in Xen through 4.11.x. The logic in oxenstored for handling writes depended on the order of evaluation of expressions making up a tuple. As indicated in section 7.7.3 "Operations on data structures" of the OCaml manual, the order of evaluation of subexpres | |
| CVE-2018-15469 | Med | 6.5 | < 4.15.1_01-1.2 | 4.15.1_01-1.2 | Aug 17, 2018 | An issue was discovered in Xen through 4.11.x. ARM never properly implemented grant table v2, either in the hypervisor or in Linux. Unfortunately, an ARM guest can still request v2 grant tables; they will simply not be properly set up, resulting in subsequent grant-related hyperc | |
| CVE-2018-15468 | Med | 6.0 | < 4.15.1_01-1.2 | 4.15.1_01-1.2 | Aug 17, 2018 | An issue was discovered in Xen through 4.11.x. The DEBUGCTL MSR contains several debugging features, some of which virtualise cleanly, but some do not. In particular, Branch Trace Store is not virtualised by the processor, and software has to be careful to configure it suitably n | |
| CVE-2018-3646 | Med | 5.6 | < 4.15.1_01-1.2 | 4.15.1_01-1.2 | Aug 14, 2018 | Systems with microprocessors utilizing speculative execution and address translations may allow unauthorized disclosure of information residing in the L1 data cache to an attacker with local user access with guest OS privilege via a terminal page fault and a side-channel analysis | |

| CVE-2018-12893 | Med | 6.5 | < 4.15.1_01-1.2 | 4.15.1_01-1.2 | Jul 2, 2018 | An issue was discovered in Xen through 4.10.x. One of the fixes in XSA-260 added some safety checks to help prevent Xen livelocking with debug exceptions. Unfortunately, due to an oversight, at least one of these safety checks can be triggered by a guest. A malicious PV guest can | |
| CVE-2018-12892 | Cri | 9.9 | < 4.15.1_01-1.2 | 4.15.1_01-1.2 | Jul 2, 2018 | An issue was discovered in Xen 4.7 through 4.10.x. libxl fails to pass the readonly flag to qemu when setting up a SCSI disk, due to what was probably an erroneous merge conflict resolution. Malicious guest administrators or (in some situations) users may be able to write to supp | |
| CVE-2018-12891 | Med | 6.5 | < 4.15.1_01-1.2 | 4.15.1_01-1.2 | Jul 2, 2018 | An issue was discovered in Xen through 4.10.x. Certain PV MMU operations may take a long time to process. For that reason Xen explicitly checks for the need to preempt the current vCPU at certain points. A few rarely taken code paths did bypass such checks. By suitably enforcing | |
