CVE-2016-9383 2 Citrix, Xen 2 Xenserver, Xen 2025-04-20 7.2 HIGH 8.8 HIGH
Xen, when running on a 64-bit hypervisor, allows local x86 guest OS users to modify arbitrary memory and consequently obtain sensitive information, cause a denial of service (host crash), or execute arbitrary code on the host by leveraging broken emulation of bit test instructions.
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-2016-9818 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 crash) via vectors involving an asynchronous abort while at HYP.
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-2017-10916 1 Xen 1 Xen 2025-04-20 5.0 MEDIUM 7.5 HIGH
The vCPU context-switch implementation in Xen through 4.8.x improperly interacts with the Memory Protection Extensions (MPX) and Protection Key (PKU) features, which makes it easier for guest OS users to defeat ASLR and other protection mechanisms, aka XSA-220.
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-2017-10912 1 Xen 1 Xen 2025-04-20 10.0 HIGH 10.0 CRITICAL
Xen through 4.8.x mishandles page transfer, which allows guest OS users to obtain privileged host OS access, aka XSA-217.
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-2017-17563 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 an incorrect mask for reference-count overflow checking in shadow mode.
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-2016-9382 2 Citrix, Xen 2 Xenserver, Xen 2025-04-20 4.6 MEDIUM 7.8 HIGH
Xen 4.0.x through 4.7.x mishandle x86 task switches to VM86 mode, which allows local 32-bit x86 HVM guest OS users to gain privileges or cause a denial of service (guest OS crash) by leveraging a guest operating system that uses hardware task switching and allows a new task to start in VM86 mode.
CVE-2017-15592 1 Xen 1 Xen 2025-04-20 7.2 HIGH 8.8 HIGH
An issue was discovered in Xen through 4.9.x allowing x86 HVM guest OS users to cause a denial of service (hypervisor crash) or possibly gain privileges because self-linear shadow mappings are mishandled for translated guests.
CVE-2017-17045 1 Xen 1 Xen 2025-04-20 7.2 HIGH 8.8 HIGH
An issue was discovered in Xen through 4.9.x allowing HVM guest OS users to gain privileges on the host OS, obtain sensitive information, or cause a denial of service (BUG and host OS crash) by leveraging the mishandling of Populate on Demand (PoD) Physical-to-Machine (P2M) errors.
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-2016-9377 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 IDT entry miscalculation.
CVE-2023-34321 1 Xen 1 Xen 2025-04-17 N/A 3.3 LOW
Arm provides multiple helpers to clean & invalidate the cache for a given region. This is, for instance, used when allocating guest memory to ensure any writes (such as the ones during scrubbing) have reached memory before handing over the page to a guest. Unfortunately, the arithmetics in the helpers can overflow and would then result to skip the cache cleaning/invalidation. Therefore there is no guarantee when all the writes will reach the memory.
CVE-2015-5154 4 Fedoraproject, Qemu, Suse and 1 more 8 Fedora, Qemu, Linux Enterprise Debuginfo and 5 more 2025-04-12 7.2 HIGH N/A
Heap-based buffer overflow in the IDE subsystem in QEMU, as used in Xen 4.5.x and earlier, when the container has a CDROM drive enabled, allows local guest users to execute arbitrary code on the host via unspecified ATAPI commands.
CVE-2014-1894 1 Xen 1 Xen 2025-04-12 5.2 MEDIUM 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-2014-8594 3 Debian, Opensuse, Xen 3 Debian Linux, Opensuse, Xen 2025-04-12 5.4 MEDIUM N/A
The do_mmu_update function in arch/x86/mm.c in Xen 4.x through 4.4.x does not properly restrict updates to only PV page tables, which allows remote PV guests to cause a denial of service (NULL pointer dereference) by leveraging hardware emulation services for HVM guests using Hardware Assisted Paging (HAP).
CVE-2016-7094 1 Xen 1 Xen 2025-04-12 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.
