CVE-2017-10914 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
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-2016-10013 | 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-2016-9380 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
The pygrub boot loader emulator in Xen, when nul-delimited output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via NUL bytes in the bootloader configuration file. | ||||
CVE-2016-9382 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
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-2016-10025 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
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-2017-12136 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2025-04-20 | N/A |
Race condition in the grant table code in Xen 4.6.x through 4.9.x allows local guest OS administrators to cause a denial of service (free list corruption and host crash) or gain privileges on the host via vectors involving maptrack free list handling. | ||||
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-2016-9385 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
The x86 segment base write emulation functionality in Xen 4.4.x through 4.7.x allows local x86 PV guest OS administrators to cause a denial of service (host crash) by leveraging lack of canonical address checks. | ||||
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-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-2016-9377 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
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-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-2017-14316 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
A parameter verification issue was discovered in Xen through 4.9.x. The function `alloc_heap_pages` allows callers to specify the first NUMA node that should be used for allocations through the `memflags` parameter; the node is extracted using the `MEMF_get_node` macro. While the function checks to see if the special constant `NUMA_NO_NODE` is specified, it otherwise does not handle the case where `node >= MAX_NUMNODES`. This allows an out-of-bounds access to an internal array. | ||||
CVE-2017-14317 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
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 | N/A |
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-2017-15593 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to cause a denial of service (memory leak) because reference counts are mishandled. | ||||
CVE-2017-10918 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
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-2017-15596 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
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-2016-9384 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
Xen 4.7 allows local guest OS users to obtain sensitive host information by loading a 32-bit ELF symbol table. | ||||
CVE-2017-10916 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
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. |
