|---|---|---|---|
| 2019-10-31 | CVE-2019-18423 | Off-by-one Error vulnerability in multiple products An issue was discovered in Xen through 4.12.x allowing ARM guest OS users to cause a denial of service via a XENMEM_add_to_physmap hypercall. | 8.8 |
| 2019-10-31 | CVE-2019-18422 | Incorrect Permission Assignment for Critical Resource vulnerability in multiple products 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. | 8.8 |
| 2019-10-31 | CVE-2019-18421 | Race Condition vulnerability in multiple products An issue was discovered in Xen through 4.12.x allowing x86 PV guest OS users to gain host OS privileges by leveraging race conditions in pagetable promotion and demotion operations. | 7.5 |
| 2019-10-08 | CVE-2019-17347 | Improper Input Validation vulnerability in multiple products An issue was discovered in Xen through 4.11.x allowing x86 PV guest OS users to cause a denial of service or gain privileges because a guest can manipulate its virtualised %cr4 in a way that is incompatible with Linux (and possibly other guest kernels). | 7.8 |
| 2019-10-08 | CVE-2019-17346 | Improper Input Validation vulnerability in multiple products An issue was discovered in Xen through 4.11.x allowing x86 PV guest OS users to cause a denial of service or gain privileges because of an incompatibility between Process Context Identifiers (PCID) and TLB flushes. | 8.8 |
| 2019-10-08 | CVE-2019-17342 | Race Condition vulnerability in multiple products An issue was discovered in Xen through 4.11.x allowing x86 PV guest OS users to cause a denial of service or gain privileges by leveraging a race condition that arose when XENMEM_exchange was introduced. | 7.0 |
| 2019-10-08 | CVE-2019-17341 | Race Condition vulnerability in multiple products An issue was discovered in Xen through 4.11.x allowing x86 PV guest OS users to cause a denial of service or gain privileges by leveraging a page-writability race condition during addition of a passed-through PCI device. | 7.8 |
| 2018-12-08 | CVE-2018-19966 | Interpretation Conflict vulnerability in multiple products 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. | 8.8 |
| 2018-12-08 | CVE-2018-19962 | Information Exposure vulnerability in multiple products 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 small IOMMU mappings are unsafely combined into larger ones. | 7.8 |
| 2018-12-08 | CVE-2018-19961 | Incomplete Cleanup vulnerability in multiple products 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. | 7.8 |
