| CVE-2014-7188 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The hvm_msr_read_intercept function in arch/x86/hvm/hvm.c in Xen 4.1 through 4.4.x uses an improper MSR range for x2APIC emulation, which allows local HVM guests to cause a denial of service (host crash) or read data from the hypervisor or other guests via unspecified vectors. | ||||
| CVE-2014-7156 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The x86_emulate function in arch/x86/x86_emulate/x86_emulate.c in Xen 3.3.x through 4.4.x does not check the supervisor mode permissions for instructions that generate software interrupts, which allows local HVM guest users to cause a denial of service (guest crash) via unspecified vectors. | ||||
| 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-2014-7155 | 4 Debian, Fedoraproject, Opensuse and 1 more | 4 Debian Linux, Fedora, Opensuse and 1 more | 2025-04-12 | N/A |
| The x86_emulate function in arch/x86/x86_emulate/x86_emulate.c in Xen 4.4.x and earlier does not properly check supervisor mode permissions, which allows local HVM users to cause a denial of service (guest crash) or gain guest kernel mode privileges via vectors involving an (1) HLT, (2) LGDT, (3) LIDT, or (4) LMSW instruction. | ||||
| CVE-2014-6268 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The evtchn_fifo_set_pending function in Xen 4.4.x allows local guest users to cause a denial of service (host crash) via vectors involving an uninitialized FIFO-based event channel control block when (1) binding or (2) moving an event to a different VCPU. | ||||
| CVE-2014-5147 | 1 Xen | 1 Xen | 2025-04-12 | 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-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-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. | ||||
