| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2019-10-08 | CVE-2019-17350 | Infinite Loop vulnerability in multiple products An issue was discovered in Xen through 4.12.x allowing Arm domU attackers to cause a denial of service (infinite loop) involving a compare-and-exchange operation. | 5.5 |
| 2018-12-08 | CVE-2018-19967 | Improper Input Validation vulnerability in multiple products An issue was discovered in Xen through 4.11.x on Intel x86 platforms allowing guest OS users to cause a denial of service (host OS hang) because Xen does not work around Intel's mishandling of certain HLE transactions associated with the KACQUIRE instruction prefix. | 6.5 |
| 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-2018-19965 | An issue was discovered in Xen through 4.11.x allowing 64-bit PV guest OS users to cause a denial of service (host OS crash) because #GP[0] can occur after a non-canonical address is passed to the TLB flushing code. | 5.6 |
| 2018-12-08 | CVE-2018-19964 | Unspecified vulnerability in XEN 4.11.0/4.11.1 An issue was discovered in Xen 4.11.x allowing x86 guest OS users to cause a denial of service (host OS hang) because the p2m lock remains unavailable indefinitely in certain error conditions. | 6.5 |
| 2018-12-08 | CVE-2018-19963 | Reachable Assertion vulnerability in XEN 4.11.0 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. | 7.8 |
| 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 |
| 2018-11-01 | CVE-2018-18883 | NULL Pointer Dereference vulnerability in XEN 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. | 8.8 |
| 2018-08-17 | CVE-2018-15471 | Out-of-bounds Read vulnerability in multiple products An issue was discovered in xenvif_set_hash_mapping in drivers/net/xen-netback/hash.c in the Linux kernel through 4.18.1, as used in Xen through 4.11.x and other products. | 7.8 |
