|---|---|---|---|---|
| CVE-2015-6654 | 1 Xen | 1 Xen | 2025-04-12 | 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-2015-5166 | 2 Fedoraproject, Xen | 2 Fedora, Xen | 2025-04-12 | N/A |
| Use-after-free vulnerability in QEMU in Xen 4.5.x and earlier does not completely unplug emulated block devices, which allows local HVM guest users to gain privileges by unplugging a block device twice. | ||||
| 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-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-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-2015-3340 | 5 Debian, Fedoraproject, Opensuse and 2 more | 9 Debian Linux, Fedora, Opensuse and 6 more | 2025-04-12 | N/A |
| Xen 4.2.x through 4.5.x does not initialize certain fields, which allows certain remote service domains to obtain sensitive information from memory via a (1) XEN_DOMCTL_gettscinfo or (2) XEN_SYSCTL_getdomaininfolist request. | ||||
| CVE-2015-3259 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Stack-based buffer overflow in the xl command line utility in Xen 4.1.x through 4.5.x allows local guest administrators to gain privileges via a long configuration argument. | ||||
| CVE-2016-3159 | 4 Debian, Fedoraproject, Oracle and 1 more | 4 Debian Linux, Fedora, Vm Server and 1 more | 2025-04-12 | N/A |
| 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-2014-4021 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-12 | N/A |
| Xen 3.2.x through 4.4.x does not properly clean memory pages recovered from guests, which allows local guest OS users to obtain sensitive information via unspecified vectors. | ||||
| 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-2015-2756 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2025-04-12 | N/A |
| QEMU, as used in Xen 3.3.x through 4.5.x, does not properly restrict access to PCI command registers, which might allow local HVM guest users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response. | ||||
| CVE-2015-2752 | 2 Fedoraproject, Xen | 2 Fedora, Xen | 2025-04-12 | N/A |
| The XEN_DOMCTL_memory_mapping hypercall in Xen 3.2.x through 4.5.x, when using a PCI passthrough device, is not preemptible, which allows local x86 HVM domain users to cause a denial of service (host CPU consumption) via a crafted request to the device model (qemu-dm). | ||||
| CVE-2015-2751 | 2 Fedoraproject, Xen | 2 Fedora, Xen | 2025-04-12 | N/A |
| Xen 4.3.x, 4.4.x, and 4.5.x, when using toolstack disaggregation, allows remote domains with partial management control to cause a denial of service (host lock) via unspecified domctl operations. | ||||
| CVE-2014-3124 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The HVMOP_set_mem_type control in Xen 4.1 through 4.4.x allows local guest HVM administrators to cause a denial of service (hypervisor crash) or possibly execute arbitrary code by leveraging a separate qemu-dm vulnerability to trigger invalid page table translations for unspecified memory page types. | ||||
| CVE-2015-8338 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Xen 4.6.x and earlier does not properly enforce limits on page order inputs for the (1) XENMEM_increase_reservation, (2) XENMEM_populate_physmap, (3) XENMEM_exchange, and possibly other HYPERVISOR_memory_op suboperations, which allows ARM guest OS administrators to cause a denial of service (CPU consumption, guest reboot, or watchdog timeout and host reboot) and possibly have unspecified other impact via unknown vectors. | ||||
| CVE-2014-8866 | 3 Debian, Opensuse, Xen | 3 Debian Linux, Opensuse, Xen | 2025-04-12 | N/A |
| The compatibility mode hypercall argument translation in Xen 3.3.x through 4.4.x, when running on a 64-bit hypervisor, allows local 32-bit HVM guests to cause a denial of service (host crash) via vectors involving altering the high halves of registers while in 64-bit mode. | ||||
| CVE-2012-6030 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The do_tmem_op function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 allow local guest OS users to cause a denial of service (host crash) and possibly have other unspecified impacts via unspecified vectors related to "broken locking checks" in an "error path." NOTE: this issue was originally published as part of CVE-2012-3497, which was too general; CVE-2012-3497 has been SPLIT into this ID and others. | ||||
| CVE-2012-5634 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.2.x, 4.1.x, and 4.0, when using Intel VT-d for PCI passthrough, does not properly configure VT-d when supporting a device that is behind a legacy PCI Bridge, which allows local guests to cause a denial of service to other guests by injecting an interrupt. | ||||
