| CVE-2016-9378 | 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 an incorrect choice for software interrupt delivery. | |||||
| CVE-2016-9815 | 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 panic) by sending an asynchronous abort. | |||||
| CVE-2017-17046 | 1 Xen | 1 Xen | 2025-04-20 | 2.1 LOW | 6.5 MEDIUM |
| An issue was discovered in Xen through 4.9.x on the ARM platform allowing guest OS users to obtain sensitive information from DRAM after a reboot, because disjoint blocks, and physical addresses that do not start at zero, are mishandled. | |||||
| CVE-2016-10013 | 1 Xen | 1 Xen | 2025-04-20 | 4.6 MEDIUM | 7.8 HIGH |
| 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-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-2017-15594 | 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-2016-9384 | 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-2017-15591 | 1 Xen | 1 Xen | 2025-04-20 | 4.9 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Xen 4.5.x through 4.9.x allowing attackers (who control a stub domain kernel or tool stack) to cause a denial of service (host OS crash) because of a missing comparison (of range start to range end) within the DMOP map/unmap implementation. | |||||
| CVE-2017-17564 | 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 incorrect error handling for reference counting in shadow mode. | |||||
| CVE-2017-8905 | 1 Xen | 1 Xen | 2025-04-20 | 6.8 MEDIUM | 8.8 HIGH |
| Xen through 4.6.x on 64-bit platforms mishandles a failsafe callback, which might allow PV guest OS users to execute arbitrary code on the host OS, aka XSA-215. | |||||
| 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-2017-12135 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2025-04-20 | 4.6 MEDIUM | 8.8 HIGH |
| 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-2016-9816 | 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 EL2. | |||||
| CVE-2017-8903 | 1 Xen | 1 Xen | 2025-04-20 | 7.2 HIGH | 8.8 HIGH |
| 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-2017-7995 | 3 Novell, Suse, Xen | 6 Suse Linux Enterprise Point Of Sale, Suse Linux Enterprise Server, Manager and 3 more | 2025-04-20 | 1.7 LOW | 3.8 LOW |
| Xen PV guest before Xen 4.3 checked access permissions to MMIO ranges only after accessing them, allowing host PCI device space memory reads, leading to information disclosure. This is an error in the get_user function. NOTE: the upstream Xen Project considers versions before 4.5.x to be EOL. | |||||
| CVE-2017-17565 | 1 Xen | 1 Xen | 2025-04-20 | 4.7 MEDIUM | 5.6 MEDIUM |
| An issue was discovered in Xen through 4.9.x allowing PV guest OS users to cause a denial of service (host OS crash) if shadow mode and log-dirty mode are in place, because of an incorrect assertion related to M2P. | |||||
| CVE-2017-17566 | 1 Xen | 1 Xen | 2025-04-20 | 6.9 MEDIUM | 7.8 HIGH |
| 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-2016-9379 | 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-2017-15597 | 1 Xen | 1 Xen | 2025-04-20 | 9.0 HIGH | 9.1 CRITICAL |
| 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. | |||||
