| An issue was discovered in Xen through 4.9.x allowing x86 guest OS users to cause a denial of service (hypervisor crash) or possibly gain privileges because MSI mapping was mishandled. | |||||
| 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-2016-9932 | 1 Xen | 1 Xen | 2025-04-20 | 2.1 LOW | 3.3 LOW |
| 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-2017-10919 | 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-2017-12855 | 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-2017-17045 | 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-2016-9379 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | 4.6 MEDIUM | 7.9 HIGH |
| 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-2017-15589 | 1 Xen | 1 Xen | 2025-04-20 | 2.1 LOW | 6.5 MEDIUM |
| An issue was discovered in Xen through 4.9.x allowing x86 HVM guest OS users to obtain sensitive information from the host OS (or an arbitrary guest OS) because intercepted I/O operations can cause a write of data from uninitialized hypervisor stack memory. | |||||
| CVE-2017-17044 | 1 Xen | 1 Xen | 2025-04-20 | 4.9 MEDIUM | 6.5 MEDIUM |
| 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. | |||||

| 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-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-2016-9816 | 1 Xen | 1 Xen | 2025-04-20 | 4.9 MEDIUM | 6.5 MEDIUM |
