CVE-2016-3158 3 Fedoraproject, Oracle, Xen 3 Fedora, Vm Server, Xen 2025-04-12 N/A
The xrstor function in arch/x86/xstate.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-2014-3125 1 Xen 1 Xen 2025-04-12 N/A
Xen 4.4.x, when running on an ARM system, does not properly context switch the CNTKCTL_EL1 register, which allows local guest users to modify the hardware timers and cause a denial of service (crash) via unspecified vectors.

Xen 3.2.x through 4.4.x does not properly clean memory pages recovered from guests, which allows local guest OS users to obtain sensitive information via unspecified vectors.
CVE-2014-3968 2 Opensuse, Xen 2 Opensuse, Xen 2025-04-12 N/A
The HVMOP_inject_msi function in Xen 4.2.x, 4.3.x, and 4.4.x allows local guest HVM administrators to cause a denial of service (host crash) via a large number of crafted requests, which trigger an error messages to be logged.
CVE-2014-2915 1 Xen 1 Xen 2025-04-12 N/A
Xen 4.4.x, when running on ARM systems, does not properly restrict access to hardware features, which allows local guest users to cause a denial of service (host or guest crash) via unspecified vectors, related to (1) cache control, (2) coprocessors, (3) debug registers, and (4) other unspecified registers.
CVE-2014-8595 3 Debian, Opensuse, Xen 3 Debian Linux, Opensuse, Xen 2025-04-12 N/A
arch/x86/x86_emulate/x86_emulate.c in Xen 3.2.1 through 4.4.x does not properly check privileges, which allows local HVM guest users to gain privileges or cause a denial of service (crash) via a crafted (1) CALL, (2) JMP, (3) RETF, (4) LCALL, (5) LJMP, or (6) LRET far branch instruction.
CVE-2015-5165 7 Arista, Debian, Fedoraproject and 4 more 25 Eos, Debian Linux, Fedora and 22 more 2025-04-12 N/A
The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors.
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-2014-1894 1 Xen 1 Xen 2025-04-12 N/A
Multiple integer overflows in unspecified suboperations in the flask hypercall in Xen 3.2.x and earlier, when XSM is enabled, allow local users to cause a denial of service (processor fault) via unspecified vectors, a different vulnerability than CVE-2014-1891, CVE-2014-1892, and CVE-2014-1893.
CVE-2016-3157 2 Canonical, Xen 2 Ubuntu Linux, Xen 2025-04-12 N/A
The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel does not properly context-switch IOPL on 64-bit PV Xen guests, which allows local guest OS users to gain privileges, cause a denial of service (guest OS crash), or obtain sensitive information by leveraging I/O port access.
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-2011-3346 3 Qemu, Redhat, Xen 3 Qemu, Enterprise Linux, Xen 2025-04-12 N/A
Buffer overflow in hw/scsi-disk.c in the SCSI subsystem in QEMU before 0.15.2, as used by Xen, might allow local guest users with permission to access the CD-ROM to cause a denial of service (guest crash) via a crafted SAI READ CAPACITY SCSI command. NOTE: this is only a vulnerability when root has manually modified certain permissions or ACLs.
CVE-2014-3967 2 Opensuse, Xen 2 Opensuse, Xen 2025-04-12 N/A
The HVMOP_inject_msi function in Xen 4.2.x, 4.3.x, and 4.4.x does not properly check the return value from the IRQ setup check, which allows local HVM guest administrators to cause a denial of service (NULL pointer dereference and crash) via unspecified vectors.
CVE-2015-4164 1 Xen 1 Xen 2025-04-12 N/A
The compat_iret function in Xen 3.1 through 4.5 iterates the wrong way through a loop, which allows local 32-bit PV guest administrators to cause a denial of service (large loop and system hang) via a hypercall_iret call with EFLAGS.VM set.
CVE-2016-2270 4 Debian, Fedoraproject, Oracle and 1 more 4 Debian Linux, Fedora, Vm Server and 1 more 2025-04-12 N/A
Xen 4.6.x and earlier allows local guest administrators to cause a denial of service (host reboot) via vectors related to multiple mappings of MMIO pages with different cachability settings.
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-2014-3969 1 Xen 1 Xen 2025-04-12 N/A
Xen 4.4.x, when running on an ARM system, does not properly check write permissions on virtual addresses, which allows local guest administrators to gain privileges via unspecified vectors.
CVE-2015-8338 1 Xen 1 Xen 2025-04-12 N/A
Xen 4.6.x and earlier does not properly enforce limits on page order inputs for the (1) XENMEM_increase_reservation, (2) XENMEM_populate_physmap, (3) XENMEM_exchange, and possibly other HYPERVISOR_memory_op suboperations, which allows ARM guest OS administrators to cause a denial of service (CPU consumption, guest reboot, or watchdog timeout and host reboot) and possibly have unspecified other impact via unknown vectors.
