| CVE-2014-1891 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Multiple integer overflows in the (1) FLASK_GETBOOL, (2) FLASK_SETBOOL, (3) FLASK_USER, and (4) FLASK_CONTEXT_TO_SID suboperations in the flask hypercall in Xen 4.3.x, 4.2.x, 4.1.x, 3.2.x, and earlier, when XSM is enabled, allow local users to cause a denial of service (processor fault) via unspecified vectors, a different vulnerability than CVE-2014-1892, CVE-2014-1893, and CVE-2014-1894. | ||||
| 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. | ||||
| 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-2016-3158 | 3 Fedoraproject, Oracle, Xen | 3 Fedora, Vm Server, Xen | 2025-04-12 | N/A |
| The xrstor function in arch/x86/xstate.c in Xen 4.x does not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors, which allows local guest OS users to obtain sensitive register content information from another guest by leveraging pending exception and mask bits. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-2076. | ||||
| 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-2015-7311 | 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. | ||||
