| CVE-2017-15588 | 1 Xen | 1 Xen | 2025-04-20 | 6.9 MEDIUM | 7.8 HIGH |
| 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-2017-10913 | 1 Xen | 1 Xen | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
| The grant-table feature in Xen through 4.8.x provides false mapping information in certain cases of concurrent unmap calls, which allows backend attackers to obtain sensitive information or gain privileges, aka XSA-218 bug 1. | |||||
| 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-2015-7504 | 3 Debian, Qemu, Xen | 3 Debian Linux, Qemu, Xen | 2025-04-20 | 4.6 MEDIUM | 8.8 HIGH |

| CVE-2017-7228 | 1 Xen | 1 Xen | 2025-04-20 | 7.2 HIGH | 8.2 HIGH |
| 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-2017-15591 | 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-2017-8905 | 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-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-2017-10912 | 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-2016-9818 | 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 HYP. | |||||
| 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-2016-10024 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | 4.9 MEDIUM | 6.0 MEDIUM |
| 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-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-2017-12134 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | 7.2 HIGH | 8.8 HIGH |
| 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-2017-10923 | 1 Xen | 1 Xen | 2025-04-20 | 5.0 MEDIUM | 6.5 MEDIUM |
| 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-2017-15595 | 1 Xen | 1 Xen | 2025-04-20 | 7.2 HIGH | 8.8 HIGH |
| 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-2016-9385 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | 4.9 MEDIUM | 6.0 MEDIUM |
| 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-2017-10917 | 1 Xen | 1 Xen | 2025-04-20 | 9.4 HIGH | 9.1 CRITICAL |
| 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-2017-15597 | 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. | |||||
| CVE-2016-9386 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | 4.6 MEDIUM | 7.8 HIGH |
| 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. | |||||
