CVE-2015-8553 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-12 | N/A |
Xen allows guest OS users to obtain sensitive information from uninitialized locations in host OS kernel memory by not enabling memory and I/O decoding control bits. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-0777. | ||||
CVE-2014-1895 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
Off-by-one error in the flask_security_avc_cachestats function in xsm/flask/flask_op.c in Xen 4.2.x and 4.3.x, when the maximum number of physical CPUs are in use, allows local users to cause a denial of service (host crash) or obtain sensitive information from hypervisor memory by leveraging a FLASK_AVC_CACHESTAT hypercall, which triggers a buffer over-read. | ||||
CVE-2015-8552 | 4 Canonical, Debian, Novell and 1 more | 5 Ubuntu Linux, Debian Linux, Suse Linux Enterprise Debuginfo and 2 more | 2025-04-12 | N/A |
The PCI backend driver in Xen, when running on an x86 system and using Linux 3.1.x through 4.3.x as the driver domain, allows local guest administrators to generate a continuous stream of WARN messages and cause a denial of service (disk consumption) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and XEN_PCI_OP_enable_msi operations, aka "Linux pciback missing sanity checks." | ||||
CVE-2015-8550 | 2 Novell, Xen | 2 Suse Linux Enterprise Real Time Extension, Xen | 2025-04-12 | N/A |
Xen, when used on a system providing PV backends, allows local guest OS administrators to cause a denial of service (host OS crash) or gain privileges by writing to memory shared between the frontend and backend, aka a double fetch vulnerability. | ||||
CVE-2015-8341 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
The libxl toolstack library in Xen 4.1.x through 4.6.x does not properly release mappings of files used as kernels and initial ramdisks when managing multiple domains in the same process, which allows attackers to cause a denial of service (memory and disk consumption) by starting domains. | ||||
CVE-2015-8340 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
The memory_exchange function in common/memory.c in Xen 3.2.x through 4.6.x does not properly release locks, which might allow guest OS administrators to cause a denial of service (deadlock or host crash) via unspecified vectors, related to XENMEM_exchange error handling. | ||||
CVE-2015-8339 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
The memory_exchange function in common/memory.c in Xen 3.2.x through 4.6.x does not properly hand back pages to a domain, which might allow guest OS administrators to cause a denial of service (host crash) via unspecified vectors related to domain teardown. | ||||
CVE-2015-0777 | 2 Linux, Xen | 2 Linux Kernel, Xen | 2025-04-12 | N/A |
drivers/xen/usbback/usbback.c in linux-2.6.18-xen-3.4.0 (aka the Xen 3.4.x support patches for the Linux kernel 2.6.18), as used in the Linux kernel 2.6.x and 3.x in SUSE Linux distributions, allows guest OS users to obtain sensitive information from uninitialized locations in host OS kernel memory via unspecified vectors. | ||||
CVE-2015-7971 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
Xen 3.2.x through 4.6.x does not limit the number of printk console messages when logging certain pmu and profiling hypercalls, which allows local guests to cause a denial of service via a sequence of crafted (1) HYPERCALL_xenoprof_op hypercalls, which are not properly handled in the do_xenoprof_op function in common/xenoprof.c, or (2) HYPERVISOR_xenpmu_op hypercalls, which are not properly handled in the do_xenpmu_op function in arch/x86/cpu/vpmu.c. | ||||
CVE-2015-7970 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
The p2m_pod_emergency_sweep function in arch/x86/mm/p2m-pod.c in Xen 3.4.x, 3.5.x, and 3.6.x is not preemptible, which allows local x86 HVM guest administrators to cause a denial of service (CPU consumption and possibly reboot) via crafted memory contents that triggers a "time-consuming linear scan," related to Populate-on-Demand. | ||||
CVE-2015-7835 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
The mod_l2_entry function in arch/x86/mm.c in Xen 3.4 through 4.6.x does not properly validate level 2 page table entries, which allows local PV guest administrators to gain privileges via a crafted superpage mapping. | ||||
CVE-2015-7814 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
Race condition in the relinquish_memory function in arch/arm/domain.c in Xen 4.6.x and earlier allows local domains with partial management control to cause a denial of service (host crash) via vectors involving the destruction of a domain and using XENMEM_decrease_reservation to reduce the memory of the domain. | ||||
CVE-2015-7812 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
The hypercall_create_continuation function in arch/arm/domain.c in Xen 4.4.x through 4.6.x allows local guest users to cause a denial of service (host crash) via a preemptible hypercall to the multicall interface. | ||||
CVE-2016-3157 | 2 Canonical, Xen | 2 Ubuntu Linux, Xen | 2025-04-12 | N/A |
The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel does not properly context-switch IOPL on 64-bit PV Xen guests, which allows local guest OS users to gain privileges, cause a denial of service (guest OS crash), or obtain sensitive information by leveraging I/O port access. | ||||
CVE-2015-7311 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
libxl in Xen 4.1.x through 4.6.x does not properly handle the readonly flag on disks when using the qemu-xen device model, which allows local guest users to write to a read-only disk image. | ||||
CVE-2015-4164 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
The compat_iret function in Xen 3.1 through 4.5 iterates the wrong way through a loop, which allows local 32-bit PV guest administrators to cause a denial of service (large loop and system hang) via a hypercall_iret call with EFLAGS.VM set. | ||||
CVE-2015-4163 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
GNTTABOP_swap_grant_ref in Xen 4.2 through 4.5 does not check the grant table operation version, which allows local guest domains to cause a denial of service (NULL pointer dereference) via a hypercall without a GNTTABOP_setup_table or GNTTABOP_set_version. | ||||
CVE-2015-4105 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
Xen 3.3.x through 4.5.x enables logging for PCI MSI-X pass-through error messages, which allows local x86 HVM guests to cause a denial of service (host disk consumption) via certain invalid operations. | ||||
CVE-2015-4104 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
Xen 3.3.x through 4.5.x does not properly restrict access to PCI MSI mask bits, which allows local x86 HVM guest users to cause a denial of service (unexpected interrupt and host crash) via unspecified vectors. | ||||
CVE-2014-2580 | 1 Xen | 1 Xen | 2025-04-12 | 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. |
