| CVE-2017-15597 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| An issue was discovered in Xen through 4.9.x. Grant copying code made an implication that any grant pin would be accompanied by a suitable page reference. Other portions of code, however, did not match up with that assumption. When such a grant copy operation is being done on a grant of a dying domain, the assumption turns out wrong. A malicious guest administrator can cause hypervisor memory corruption, most likely resulting in host crash and a Denial of Service. Privilege escalation and information leaks cannot be ruled out. | ||||
| 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-2015-7504 | 4 Debian, Qemu, Redhat and 1 more | 5 Debian Linux, Qemu, Enterprise Linux and 2 more | 2025-04-20 | 8.8 High |
| Heap-based buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU allows guest OS administrators to cause a denial of service (instance crash) or possibly execute arbitrary code via a series of packets in loopback mode. | ||||
| CVE-2016-9383 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
| 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-2016-9379 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
| The pygrub boot loader emulator in Xen, when S-expression output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via string quotes and S-expressions in the bootloader configuration file. | ||||
| 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-2017-8903 | 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-2017-14431 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| Memory leak in Xen 3.3 through 4.8.x allows guest OS users to cause a denial of service (ARM or x86 AMD host OS memory consumption) by continually rebooting, because certain cleanup is skipped if no pass-through device was ever assigned, aka XSA-207. | ||||
| 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-2017-12135 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2025-04-20 | N/A |
| Xen allows local OS guest users to cause a denial of service (crash) or possibly obtain sensitive information or gain privileges via vectors involving transitive grants. | ||||
| CVE-2016-9386 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
| The x86 emulator in Xen does not properly treat x86 NULL segments as unusable when accessing memory, which might allow local HVM guest users to gain privileges via vectors involving "unexpected" base/limit values. | ||||
| 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-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-2016-9817 | 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 a (1) data or (2) prefetch abort with the ESR_EL2.EA bit set. | ||||
| CVE-2017-17044 | 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 cause a denial of service (infinite loop and host OS hang) by leveraging the mishandling of Populate on Demand (PoD) errors. | ||||
| CVE-2017-15594 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| 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-2017-10917 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| Xen through 4.8.x does not validate the port numbers of polled event channel ports, which allows guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) or possibly obtain sensitive information, aka XSA-221. | ||||
| 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-2017-10921 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| The grant-table feature in Xen through 4.8.x does not ensure sufficient type counts for a GNTMAP_device_map and GNTMAP_host_map mapping, which allows guest OS users to cause a denial of service (count mismanagement and memory corruption) or obtain privileged host OS access, aka XSA-224 bug 2. | ||||
| 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. | ||||
