CVE-2017-10923 1 Xen 1 Xen 2025-04-20 N/A
Xen through 4.8.x does not validate a vCPU array index upon the sending of an SGI, which allows guest OS users to cause a denial of service (hypervisor crash), aka XSA-225.
CVE-2017-10913 1 Xen 1 Xen 2025-04-20 N/A
The grant-table feature in Xen through 4.8.x provides false mapping information in certain cases of concurrent unmap calls, which allows backend attackers to obtain sensitive information or gain privileges, aka XSA-218 bug 1.
CVE-2016-9932 1 Xen 1 Xen 2025-04-20 N/A
CMPXCHG8B emulation in Xen 3.3.x through 4.7.x on x86 systems allows local HVM guest OS users to obtain sensitive information from host stack memory via a "supposedly-ignored" operand size prefix.
CVE-2016-9818 1 Xen 1 Xen 2025-04-20 N/A
Xen through 4.7.x allows local ARM guest OS users to cause a denial of service (host crash) via vectors involving an asynchronous abort while at HYP.
CVE-2017-10912 1 Xen 1 Xen 2025-04-20 N/A
Xen through 4.8.x mishandles page transfer, which allows guest OS users to obtain privileged host OS access, aka XSA-217.
CVE-2016-9816 1 Xen 1 Xen 2025-04-20 N/A
Xen through 4.7.x allows local ARM guest OS users to cause a denial of service (host crash) via vectors involving an asynchronous abort while at EL2.
CVE-2016-9815 1 Xen 1 Xen 2025-04-20 N/A
Xen through 4.7.x allows local ARM guest OS users to cause a denial of service (host panic) by sending an asynchronous abort.
CVE-2016-10013 1 Xen 1 Xen 2025-04-20 N/A
Xen through 4.8.x allows local 64-bit x86 HVM guest OS users to gain privileges by leveraging mishandling of SYSCALL singlestep during emulation.
CVE-2016-10024 2 Citrix, Xen 2 Xenserver, Xen 2025-04-20 N/A
Xen through 4.8.x allows local x86 PV guest OS kernel administrators to cause a denial of service (host hang or crash) by modifying the instruction stream asynchronously while performing certain kernel operations.
CVE-2017-17566 1 Xen 1 Xen 2025-04-20 N/A
An issue was discovered in Xen through 4.9.x allowing PV guest OS users to cause a denial of service (host OS crash) or gain host OS privileges in shadow mode by mapping a certain auxiliary page.
CVE-2014-9066 2 Opensuse, Xen 2 Opensuse, Xen 2025-04-12 N/A
Xen 4.4.x and earlier, when using a large number of VCPUs, does not properly handle read and write locks, which allows local x86 guest users to cause a denial of service (write denial or NMI watchdog timeout and host crash) via a large number of read requests, a different vulnerability than CVE-2014-9065.
CVE-2015-0361 2 Opensuse, Xen 2 Opensuse, Xen 2025-04-12 N/A
Use-after-free vulnerability in Xen 4.2.x, 4.3.x, and 4.4.x allows remote domains to cause a denial of service (system crash) via a crafted hypercall during HVM guest teardown.
CVE-2015-3456 3 Qemu, Redhat, Xen 7 Qemu, Enterprise Linux, Enterprise Virtualization and 4 more 2025-04-12 N/A
The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM.
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-2015-2151 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2025-04-12 N/A
The x86 emulator in Xen 3.2.x through 4.5.x does not properly ignore segment overrides for instructions with register operands, which allows local guest users to obtain sensitive information, cause a denial of service (memory corruption), or possibly execute arbitrary code via unspecified vectors.
CVE-2015-2751 2 Fedoraproject, Xen 2 Fedora, Xen 2025-04-12 N/A
Xen 4.3.x, 4.4.x, and 4.5.x, when using toolstack disaggregation, allows remote domains with partial management control to cause a denial of service (host lock) via unspecified domctl operations.
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-2016-3157 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-2016-7093 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-2015-1563 2 Fedoraproject, Xen 2 Fedora, Xen 2025-04-12 N/A
The ARM GIC distributor virtualization in Xen 4.4.x and 4.5.x allows local guests to cause a denial of service by causing a large number messages to be logged.
