| CVE-2015-2756 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2025-04-12 | N/A |
| QEMU, as used in Xen 3.3.x through 4.5.x, does not properly restrict access to PCI command registers, which might allow local HVM guest users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response. | ||||
| CVE-2014-7188 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The hvm_msr_read_intercept function in arch/x86/hvm/hvm.c in Xen 4.1 through 4.4.x uses an improper MSR range for x2APIC emulation, which allows local HVM guests to cause a denial of service (host crash) or read data from the hypervisor or other guests via unspecified vectors. | ||||
| CVE-2016-7094 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| 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 | 2025-04-12 | N/A |
| 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-2016-7154 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| 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-2016-6259 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-12 | N/A |
| 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. | ||||
| CVE-2016-6258 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-12 | N/A |
| The PV pagetable code in arch/x86/mm.c in Xen 4.7.x and earlier allows local 32-bit PV guest OS administrators to gain host OS privileges by leveraging fast-paths for updating pagetable entries. | ||||
| CVE-2016-7092 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| 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-2016-7777 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| 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-2016-4962 | 2 Oracle, Xen | 2 Vm Server, Xen | 2025-04-12 | N/A |
| The libxl device-handling in Xen 4.6.x and earlier allows local OS guest administrators to cause a denial of service (resource consumption or management facility confusion) or gain host OS privileges by manipulating information in guest controlled areas of xenstore. | ||||
| CVE-2016-4480 | 2 Oracle, Xen | 2 Vm Server, Xen | 2025-04-12 | N/A |
| The guest_walk_tables function in arch/x86/mm/guest_walk.c in Xen 4.6.x and earlier does not properly handle the Page Size (PS) page table entry bit at the L4 and L3 page table levels, which might allow local guest OS users to gain privileges via a crafted mapping of memory. | ||||
| CVE-2016-4963 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The libxl device-handling in Xen through 4.6.x allows local guest OS users with access to the driver domain to cause a denial of service (management tool confusion) by manipulating information in the backend directories in xenstore. | ||||
| CVE-2016-3960 | 3 Fedoraproject, Oracle, Xen | 3 Fedora, Vm Server, Xen | 2025-04-12 | N/A |
| Integer overflow in the x86 shadow pagetable code in Xen allows local guest OS users to cause a denial of service (host crash) or possibly gain privileges by shadowing a superpage mapping. | ||||

| The fpu_fxrstor function in arch/x86/i387.c in Xen 4.x does not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors, which allows local guest OS users to obtain sensitive register content information from another guest by leveraging pending exception and mask bits. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-2076. | ||||
| CVE-2016-3961 | 2 Canonical, Xen | 2 Ubuntu Linux, Xen | 2025-04-12 | N/A |
| Xen and the Linux kernel through 4.5.x do not properly suppress hugetlbfs support in x86 PV guests, which allows local PV guest OS users to cause a denial of service (guest OS crash) by attempting to access a hugetlbfs mapped area. | ||||
| CVE-2016-5242 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The p2m_teardown function in arch/arm/p2m.c in Xen 4.4.x through 4.6.x allows local guest OS users with access to the driver domain to cause a denial of service (NULL pointer dereference and host OS crash) by creating concurrent domains and holding references to them, related to VMID exhaustion. | ||||
