CVE-2016-10025 2 Citrix, Xen 2 Xenserver, Xen 2025-04-20 2.1 LOW 5.5 MEDIUM
VMFUNC emulation in Xen 4.6.x through 4.8.x on x86 systems using AMD virtualization extensions (aka SVM) allows local HVM guest OS users to cause a denial of service (hypervisor crash) by leveraging a missing NULL pointer check.
CVE-2017-10914 1 Xen 1 Xen 2025-04-20 6.8 MEDIUM 8.1 HIGH
The grant-table feature in Xen through 4.8.x has a race condition leading to a double free, which allows guest OS users to cause a denial of service (memory consumption), or possibly obtain sensitive information or gain privileges, aka XSA-218 bug 2.
CVE-2017-10918 1 Xen 1 Xen 2025-04-20 10.0 HIGH 10.0 CRITICAL
Xen through 4.8.x does not validate memory allocations during certain P2M operations, which allows guest OS users to obtain privileged host OS access, aka XSA-222.
CVE-2017-10913 1 Xen 1 Xen 2025-04-20 7.5 HIGH 9.8 CRITICAL
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-2017-10919 1 Xen 1 Xen 2025-04-20 5.0 MEDIUM 6.5 MEDIUM
Xen through 4.8.x mishandles virtual interrupt injection, which allows guest OS users to cause a denial of service (hypervisor crash), aka XSA-223.
CVE-2017-7228 1 Xen 1 Xen 2025-04-20 7.2 HIGH 8.2 HIGH
An issue (known as XSA-212) was discovered in Xen, with fixes available for 4.8.x, 4.7.x, 4.6.x, 4.5.x, and 4.4.x. The earlier XSA-29 fix introduced an insufficient check on XENMEM_exchange input, allowing the caller to drive hypervisor memory accesses outside of the guest provided input/output arrays.
CVE-2017-10923 1 Xen 1 Xen 2025-04-20 5.0 MEDIUM 6.5 MEDIUM
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-2017-14317 1 Xen 1 Xen 2025-04-20 4.7 MEDIUM 5.6 MEDIUM
A domain cleanup issue was discovered in the C xenstore daemon (aka cxenstored) in Xen through 4.9.x. When shutting down a VM with a stubdomain, a race in cxenstored may cause a double-free. The xenstored daemon may crash, resulting in a DoS of any parts of the system relying on it (including domain creation / destruction, ballooning, device changes, etc.).
CVE-2017-10915 1 Xen 1 Xen 2025-04-20 6.8 MEDIUM 9.0 CRITICAL
The shadow-paging feature in Xen through 4.8.x mismanages page references and consequently introduces a race condition, which allows guest OS users to obtain Xen privileges, aka XSA-219.
CVE-2016-9378 1 Xen 1 Xen 2025-04-20 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 an incorrect choice for software interrupt delivery.
CVE-2016-9815 1 Xen 1 Xen 2025-04-20 4.9 MEDIUM 6.5 MEDIUM
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-2017-17046 1 Xen 1 Xen 2025-04-20 2.1 LOW 6.5 MEDIUM
An issue was discovered in Xen through 4.9.x on the ARM platform allowing guest OS users to obtain sensitive information from DRAM after a reboot, because disjoint blocks, and physical addresses that do not start at zero, are mishandled.
CVE-2016-10013 1 Xen 1 Xen 2025-04-20 4.6 MEDIUM 7.8 HIGH
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-2017-12855 1 Xen 1 Xen 2025-04-20 2.1 LOW 6.5 MEDIUM
Xen maintains the _GTF_{read,writ}ing bits as appropriate, to inform the guest that a grant is in use. A guest is expected not to modify the grant details while it is in use, whereas the guest is free to modify/reuse the grant entry when it is not in use. Under some circumstances, Xen will clear the status bits too early, incorrectly informing the guest that the grant is no longer in use. A guest may prematurely believe that a granted frame is safely private again, and reuse it in a way which contains sensitive information, while the domain on the far end of the grant is still using the grant. Xen 4.9, 4.8, 4.7, 4.6, and 4.5 are affected.
CVE-2017-15594 1 Xen 1 Xen 2025-04-20 4.6 MEDIUM 8.8 HIGH
An issue was discovered in Xen through 4.9.x allowing x86 SVM PV guest OS users to cause a denial of service (hypervisor crash) or gain privileges because IDT settings are mishandled during CPU hotplugging.
CVE-2016-9384 1 Xen 1 Xen 2025-04-20 2.1 LOW 6.5 MEDIUM
Xen 4.7 allows local guest OS users to obtain sensitive host information by loading a 32-bit ELF symbol table.
CVE-2017-15596 1 Xen 1 Xen 2025-04-20 4.9 MEDIUM 6.0 MEDIUM
An issue was discovered in Xen 4.4.x through 4.9.x allowing ARM guest OS users to cause a denial of service (prevent physical CPU usage) because of lock mishandling upon detection of an add-to-physmap error.
CVE-2017-15591 1 Xen 1 Xen 2025-04-20 4.9 MEDIUM 6.5 MEDIUM
An issue was discovered in Xen 4.5.x through 4.9.x allowing attackers (who control a stub domain kernel or tool stack) to cause a denial of service (host OS crash) because of a missing comparison (of range start to range end) within the DMOP map/unmap implementation.
CVE-2017-17564 1 Xen 1 Xen 2025-04-20 6.9 MEDIUM 7.8 HIGH
An issue was discovered in Xen through 4.9.x allowing guest OS users to cause a denial of service (host OS crash) or gain host OS privileges by leveraging incorrect error handling for reference counting in shadow mode.
CVE-2017-8905 1 Xen 1 Xen 2025-04-20 6.8 MEDIUM 8.8 HIGH
Xen through 4.6.x on 64-bit platforms mishandles a failsafe callback, which might allow PV guest OS users to execute arbitrary code on the host OS, aka XSA-215.
