| CVE-2016-4963 | 1 Xen | 1 Xen | 2025-04-12 | 1.9 LOW | 4.7 MEDIUM |
| The libxl device-handling in Xen through 4.6.x allows local guest OS users with access to the driver domain to cause a denial of service (management tool confusion) by manipulating information in the backend directories in xenstore. | |||||
| CVE-2014-5148 | 1 Xen | 1 Xen | 2025-04-12 | 4.6 MEDIUM | N/A |
| Xen 4.4.x, when running on an ARM system and "handling an unknown system register access from 64-bit userspace," returns to an instruction of the trap handler for kernel space faults instead of an instruction that is associated with faults in 64-bit userspace, which allows local guest users to cause a denial of service (crash) and possibly gain privileges via a crafted process. | |||||
| CVE-2015-2150 | 3 Linux, Ubuntu, Xen | 3 Linux Kernel, Ubuntu, Xen | 2025-04-12 | 4.9 MEDIUM | N/A |
| Xen 3.3.x through 4.5.x and the Linux kernel through 3.19.1 do not properly restrict access to PCI command registers, which might allow local guest OS users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response. | |||||
| CVE-2014-3716 | 1 Xen | 1 Xen | 2025-04-12 | 1.9 LOW | N/A |
| Xen 4.4.x does not properly check alignment, which allows local users to cause a denial of service (crash) via an unspecified field in a DTB header in a 32-bit guest kernel. | |||||
| CVE-2015-3259 | 1 Xen | 1 Xen | 2025-04-12 | 6.8 MEDIUM | N/A |
| Stack-based buffer overflow in the xl command line utility in Xen 4.1.x through 4.5.x allows local guest administrators to gain privileges via a long configuration argument. | |||||
| CVE-2015-3456 | 3 Qemu, Redhat, Xen | 5 Qemu, Enterprise Linux, Enterprise Virtualization and 2 more | 2025-04-12 | 7.7 HIGH | N/A |
| The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM. | |||||
| CVE-2014-5147 | 1 Xen | 1 Xen | 2025-04-12 | 4.3 MEDIUM | N/A |
| Xen 4.4.x, when running a 64-bit kernel on an ARM system, does not properly handle traps from the guest domain that use a different address width, which allows local guest users to cause a denial of service (host crash) via a crafted 32-bit process. | |||||
| CVE-2014-2580 | 1 Xen | 1 Xen | 2025-04-12 | 4.4 MEDIUM | N/A |
| The netback driver in Xen, when using certain Linux versions that do not allow sleeping in softirq context, allows local guest administrators to cause a denial of service ("scheduling while atomic" error and host crash) via a malformed packet, which causes a mutex to be taken when trying to disable the interface. | |||||

| CVE-2015-8554 | 1 Xen | 1 Xen | 2025-04-12 | 6.6 MEDIUM | 7.5 HIGH |
| Buffer overflow in hw/pt-msi.c in Xen 4.6.x and earlier, when using the qemu-xen-traditional (aka qemu-dm) device model, allows local x86 HVM guest administrators to gain privileges by leveraging a system with access to a passed-through MSI-X capable physical PCI device and MSI-X table entries, related to a "write path." | |||||
| CVE-2015-6654 | 1 Xen | 1 Xen | 2025-04-12 | 2.1 LOW | N/A |
| The xenmem_add_to_physmap_one function in arch/arm/mm.c in Xen 4.5.x, 4.4.x, and earlier does not limit the number of printk console messages when reporting a failure to retrieve a reference on a foreign page, which allows remote domains to cause a denial of service by leveraging permissions to map the memory of a foreign guest. | |||||
| CVE-2011-3346 | 3 Qemu, Redhat, Xen | 3 Qemu, Enterprise Linux, Xen | 2025-04-12 | 4.0 MEDIUM | N/A |

NOTE: this is only a vulnerability when root has manually modified certain permissions or ACLs. | |||||
