The fpu_fxrstor function in arch/x86/i387.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-2014-5146 | 2 Opensuse, Xen | 2 Opensuse, Xen | 2025-04-12 | N/A |
Certain MMU virtualization operations in Xen 4.2.x through 4.4.x before the xsa97-hap patch, when using Hardware Assisted Paging (HAP), are not preemptible, which allows local HVM guest to cause a denial of service (vcpu consumption) by invoking these operations, which process every page assigned to a guest, a different vulnerability than CVE-2014-5149. | ||||
CVE-2016-3961 | 2 Canonical, Xen | 2 Ubuntu Linux, Xen | 2025-04-12 | N/A |
Xen and the Linux kernel through 4.5.x do not properly suppress hugetlbfs support in x86 PV guests, which allows local PV guest OS users to cause a denial of service (guest OS crash) by attempting to access a hugetlbfs mapped area. | ||||
CVE-2015-5165 | 7 Arista, Debian, Fedoraproject and 4 more | 25 Eos, Debian Linux, Fedora and 22 more | 2025-04-12 | N/A |
The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors. | ||||
CVE-2016-6258 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-12 | N/A |
The PV pagetable code in arch/x86/mm.c in Xen 4.7.x and earlier allows local 32-bit PV guest OS administrators to gain host OS privileges by leveraging fast-paths for updating pagetable entries. | ||||
CVE-2016-5242 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
The p2m_teardown function in arch/arm/p2m.c in Xen 4.4.x through 4.6.x allows local guest OS users with access to the driver domain to cause a denial of service (NULL pointer dereference and host OS crash) by creating concurrent domains and holding references to them, related to VMID exhaustion. | ||||
CVE-2015-5154 | 5 Fedoraproject, Qemu, Redhat and 2 more | 10 Fedora, Qemu, Enterprise Linux and 7 more | 2025-04-12 | N/A |
Heap-based buffer overflow in the IDE subsystem in QEMU, as used in Xen 4.5.x and earlier, when the container has a CDROM drive enabled, allows local guest users to execute arbitrary code on the host via unspecified ATAPI commands. | ||||
CVE-2014-4022 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
The alloc_domain_struct function in arch/arm/domain.c in Xen 4.4.x, when running on an ARM platform, does not properly initialize the structure containing the grant table pages for a domain, which allows local guest administrators to obtain sensitive information via the GNTTABOP_setup_table subhypercall. | ||||
