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 |
Buffer overflow in hw/scsi-disk.c in the SCSI subsystem in QEMU before 0.15.2, as used by Xen, might allow local guest users with permission to access the CD-ROM to cause a denial of service (guest crash) via a crafted SAI READ CAPACITY SCSI command. NOTE: this is only a vulnerability when root has manually modified certain permissions or ACLs. | |||||
CVE-2012-3433 | 1 Xen | 1 Xen | 2025-04-11 | 4.9 MEDIUM | N/A |
Xen 4.0 and 4.1 allows local HVM guest OS kernels to cause a denial of service (domain 0 VCPU hang and kernel panic) by modifying the physical address space in a way that triggers excessive shared page search time during the p2m teardown. | |||||
CVE-2013-0154 | 1 Xen | 1 Xen | 2025-04-11 | 1.9 LOW | N/A |
The get_page_type function in xen/arch/x86/mm.c in Xen 4.2, when debugging is enabled, allows local PV or HVM guest administrators to cause a denial of service (assertion failure and hypervisor crash) via unspecified vectors related to a hypercall. | |||||
CVE-2011-3131 | 1 Xen | 1 Xen | 2025-04-11 | 4.6 MEDIUM | N/A |
Xen 4.1.1 and earlier allows local guest OS kernels with control of a PCI[E] device to cause a denial of service (CPU consumption and host hang) via many crafted DMA requests that are denied by the IOMMU, which triggers a livelock. | |||||
CVE-2011-1936 | 1 Xen | 1 Xen | 2025-04-11 | 4.6 MEDIUM | N/A |
Xen, when using x86 Intel processors and the VMX virtualization extension is enabled, does not properly handle cpuid instruction emulation when exiting the VM, which allows local guest users to cause a denial of service (guest crash) via unspecified vectors. | |||||
CVE-2011-2519 | 2 Redhat, Xen | 4 Enterprise Linux Desktop, Enterprise Linux Server, Enterprise Linux Workstation and 1 more | 2025-04-11 | 5.5 MEDIUM | N/A |
Xen in the Linux kernel, when running a guest on a host without hardware assisted paging (HAP), allows guest users to cause a denial of service (invalid pointer dereference and hypervisor crash) via the SAHF instruction. | |||||
CVE-2012-5513 | 1 Xen | 1 Xen | 2025-04-11 | 6.9 MEDIUM | N/A |
The XENMEM_exchange handler in Xen 4.2 and earlier does not properly check the memory address, which allows local PV guest OS administrators to cause a denial of service (crash) or possibly gain privileges via unspecified vectors that overwrite memory in the hypervisor reserved range. | |||||
CVE-2013-1432 | 1 Xen | 1 Xen | 2025-04-11 | 7.4 HIGH | N/A |
Xen 4.1.x and 4.2.x, when the XSA-45 patch is in place, does not properly maintain references on pages stored for deferred cleanup, which allows local PV guest kernels to cause a denial of service (premature page free and hypervisor crash) or possibly gain privileges via unspecified vectors. | |||||
CVE-2012-0218 | 1 Xen | 1 Xen | 2025-04-11 | 1.9 LOW | N/A |
Xen 3.4, 4.0, and 4.1, when the guest OS has not registered a handler for a syscall or sysenter instruction, does not properly clear a flag for exception injection when injecting a General Protection Fault, which allows local PV guest OS users to cause a denial of service (guest crash) by later triggering an exception that would normally be handled within Xen. | |||||
CVE-2012-3494 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-11 | 2.1 LOW | N/A |
