CVE-2017-8903 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
Xen through 4.8.x on 64-bit platforms mishandles page tables after an IRET hypercall, which might allow PV guest OS users to execute arbitrary code on the host OS, aka XSA-213. | ||||
CVE-2017-15595 | 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 (unbounded recursion, stack consumption, and hypervisor crash) or possibly gain privileges via crafted page-table stacking. | ||||
CVE-2016-9378 | 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 an incorrect choice for software interrupt delivery. | ||||
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-2017-15596 | 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-2017-17045 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
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-2017-14318 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
An issue was discovered in Xen 4.5.x through 4.9.x. The function `__gnttab_cache_flush` handles GNTTABOP_cache_flush grant table operations. It checks to see if the calling domain is the owner of the page that is to be operated on. If it is not, the owner's grant table is checked to see if a grant mapping to the calling domain exists for the page in question. However, the function does not check to see if the owning domain actually has a grant table or not. Some special domains, such as `DOMID_XEN`, `DOMID_IO` and `DOMID_COW` are created without grant tables. Hence, if __gnttab_cache_flush operates on a page owned by these special domains, it will attempt to dereference a NULL pointer in the domain struct. | ||||
CVE-2017-12137 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2025-04-20 | N/A |
arch/x86/mm.c in Xen allows local PV guest OS users to gain host OS privileges via vectors related to map_grant_ref. | ||||
CVE-2017-15588 | 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 execute arbitrary code on the host OS because of a race condition that can cause a stale TLB entry. | ||||
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-2016-9932 | 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-2017-10914 | 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-2017-7228 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
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 | 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-2017-10916 | 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. | ||||
CVE-2017-12134 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation. | ||||
CVE-2017-12855 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
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-2017-14316 | 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-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-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. |
