| 2019-12-11 | CVE-2019-19583 | An issue was discovered in Xen through 4.12.x allowing x86 HVM/PVH guest OS users to cause a denial of service (guest OS crash) because VMX VMEntry checks mishandle a certain case. | 7.5 |
| 2019-12-11 | CVE-2019-19578 | Incorrect Calculation vulnerability in multiple products An issue was discovered in Xen through 4.12.x allowing x86 PV guest OS users to cause a denial of service via degenerate chains of linear pagetables, because of an incorrect fix for CVE-2017-15595. | 8.8 |
| 2019-12-11 | CVE-2019-19577 | Improper Synchronization vulnerability in multiple products An issue was discovered in Xen through 4.12.x allowing x86 AMD HVM guest OS users to cause a denial of service or possibly gain privileges by triggering data-structure access during pagetable-height updates. | 7.2 |
| 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 |
