|---|---|---|---|---|---|
| CVE-2017-14319 | 1 Xen | 1 Xen | 2025-04-20 | 7.2 HIGH | 8.8 HIGH |
| A grant unmapping issue was discovered in Xen through 4.9.x. When removing or replacing a grant mapping, the x86 PV specific path needs to make sure page table entries remain in sync with other accounting done. Although the identity of the page frame was validated correctly, neither the presence of the mapping nor page writability were taken into account. | |||||
| 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-2017-10922 | 1 Xen | 1 Xen | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| The grant-table feature in Xen through 4.8.x mishandles MMIO region grant references, which allows guest OS users to cause a denial of service (loss of grant trackability), aka XSA-224 bug 3. | |||||
| CVE-2016-9380 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | 4.6 MEDIUM | 7.5 HIGH |

| CVE-2017-10920 | 1 Xen | 1 Xen | 2025-04-20 | 10.0 HIGH | 10.0 CRITICAL |
| The grant-table feature in Xen through 4.8.x mishandles a GNTMAP_device_map and GNTMAP_host_map mapping, when followed by only a GNTMAP_host_map unmapping, 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 1. | |||||
| 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-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-2017-15589 | 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-2017-15592 | 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 HVM guest OS users to cause a denial of service (hypervisor crash) or possibly gain privileges because self-linear shadow mappings are mishandled for translated guests. | |||||
| 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-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. | |||||
| CVE-2017-10921 | 1 Xen | 1 Xen | 2025-04-20 | 10.0 HIGH | 10.0 CRITICAL |
| 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-2016-9382 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | 4.6 MEDIUM | 7.8 HIGH |
| Xen 4.0.x through 4.7.x mishandle x86 task switches to VM86 mode, which allows local 32-bit x86 HVM guest OS users to gain privileges or cause a denial of service (guest OS crash) by leveraging a guest operating system that uses hardware task switching and allows a new task to start in VM86 mode. | |||||
| CVE-2016-9377 | 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 IDT entry miscalculation. | |||||
| CVE-2017-15593 | 1 Xen | 1 Xen | 2025-04-20 | 4.9 MEDIUM | 6.5 MEDIUM |
| 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-2015-7504 | 3 Debian, Qemu, Xen | 3 Debian Linux, Qemu, Xen | 2025-04-20 | 4.6 MEDIUM | 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-2017-14316 | 1 Xen | 1 Xen | 2025-04-20 | 7.2 HIGH | 8.8 HIGH |
| 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-2016-9385 | 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-2017-12136 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2025-04-20 | 6.9 MEDIUM | 7.8 HIGH |
| Race condition in the grant table code in Xen 4.6.x through 4.9.x allows local guest OS administrators to cause a denial of service (free list corruption and host crash) or gain privileges on the host via vectors involving maptrack free list handling. | |||||
| 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. | |||||
