| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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. | 7.2 |
| 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 |
| 2018-07-28 | CVE-2018-14678 | Improper Initialization vulnerability in multiple products An issue was discovered in the Linux kernel through 4.17.11, as used in Xen through 4.11.x. | 7.8 |
| 2018-05-10 | CVE-2018-10982 | An issue was discovered in Xen through 4.10.x allowing x86 HVM guest OS users to cause a denial of service (unexpectedly high interrupt number, array overrun, and hypervisor crash) or possibly gain hypervisor privileges by setting up an HPET timer to deliver interrupts in IO-APIC mode, aka vHPET interrupt injection. | 7.2 |
| 2018-05-08 | CVE-2018-8897 | Race Condition vulnerability in multiple products A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. | 7.2 |
| 2017-11-28 | CVE-2017-17045 | Use After Free vulnerability in XEN An issue was discovered in Xen through 4.9.x allowing HVM guest OS users to gain privileges on the host OS, obtain sensitive information, or cause a denial of service (BUG and host OS crash) by leveraging the mishandling of Populate on Demand (PoD) Physical-to-Machine (P2M) errors. | 7.2 |
| 2017-10-18 | CVE-2017-15595 | Resource Exhaustion vulnerability in XEN An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to cause a denial of service (unbounded recursion, stack consumption, and hypervisor crash) or possibly gain privileges via crafted page-table stacking. | 7.2 |
| 2017-10-18 | CVE-2017-15592 | Exposure of Resource to Wrong Sphere vulnerability in XEN An issue was discovered in Xen through 4.9.x allowing x86 HVM guest OS users to cause a denial of service (hypervisor crash) or possibly gain privileges because self-linear shadow mappings are mishandled for translated guests. | 7.2 |
| 2017-10-16 | CVE-2015-7504 | Out-of-bounds Write vulnerability in multiple products Heap-based buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU allows guest OS administrators to cause a denial of service (instance crash) or possibly execute arbitrary code via a series of packets in loopback mode. | 8.8 |
| 2017-09-12 | CVE-2017-14319 | Unspecified vulnerability in XEN A grant unmapping issue was discovered in Xen through 4.9.x. | 7.2 |
