| Xen 4.5.x through 4.7.x on AMD systems without the NRip feature, when emulating instructions that generate software interrupts, allows local HVM guest OS users to cause a denial of service (guest crash) by leveraging an incorrect choice for software interrupt delivery. | |||||
| CVE-2016-9377 | 1 Xen | 1 Xen | 2026-06-17 | 2.1 LOW | 5.5 MEDIUM |
| Xen 4.5.x through 4.7.x on AMD systems without the NRip feature, when emulating instructions that generate software interrupts, allows local HVM guest OS users to cause a denial of service (guest crash) by leveraging IDT entry miscalculation. | |||||
| CVE-2016-7777 | 1 Xen | 1 Xen | 2026-06-17 | 3.3 LOW | 6.3 MEDIUM |
| Xen 4.7.x and earlier does not properly honor CR0.TS and CR0.EM, which allows local x86 HVM guest OS users to read or modify FPU, MMX, or XMM register state information belonging to arbitrary tasks on the guest by modifying an instruction while the hypervisor is preparing to emulate it. | |||||
| CVE-2016-7154 | 1 Xen | 1 Xen | 2026-06-17 | 7.2 HIGH | 6.7 MEDIUM |
| Use-after-free vulnerability in the FIFO event channel code in Xen 4.4.x allows local guest OS administrators to cause a denial of service (host crash) and possibly execute arbitrary code or obtain sensitive information via an invalid guest frame number. | |||||
| CVE-2016-7094 | 1 Xen | 1 Xen | 2026-06-17 | 1.5 LOW | 4.1 MEDIUM |
| Buffer overflow in Xen 4.7.x and earlier allows local x86 HVM guest OS administrators on guests running with shadow paging to cause a denial of service via a pagetable update. | |||||
| CVE-2016-7093 | 1 Xen | 1 Xen | 2026-06-17 | 7.2 HIGH | 8.2 HIGH |
| Xen 4.5.3, 4.6.3, and 4.7.x allow local HVM guest OS administrators to overwrite hypervisor memory and consequently gain host OS privileges by leveraging mishandling of instruction pointer truncation during emulation. | |||||
| CVE-2016-7092 | 1 Xen | 1 Xen | 2026-06-17 | 6.8 MEDIUM | 8.2 HIGH |
| The get_page_from_l3e function in arch/x86/mm.c in Xen allows local 32-bit PV guest OS administrators to gain host OS privileges via vectors related to L3 recursive pagetables. | |||||
| CVE-2016-6259 | 2 Citrix, Xen | 2 Xenserver, Xen | 2026-06-17 | 4.9 MEDIUM | 6.2 MEDIUM |
| Xen 4.5.x through 4.7.x do not implement Supervisor Mode Access Prevention (SMAP) whitelisting in 32-bit exception and event delivery, which allows local 32-bit PV guest OS kernels to cause a denial of service (hypervisor and VM crash) by triggering a safety check. | |||||
