|---|---|---|---|---|
| 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-2015-2151 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2025-04-12 | N/A |
| The x86 emulator in Xen 3.2.x through 4.5.x does not properly ignore segment overrides for instructions with register operands, which allows local guest users to obtain sensitive information, cause a denial of service (memory corruption), or possibly execute arbitrary code via unspecified vectors. | ||||
| CVE-2013-2195 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The Elf parser (libelf) in Xen 4.2.x and earlier allow local guest administrators with certain permissions to have an unspecified impact via a crafted kernel, related to "pointer dereferences" involving unexpected calculations. | ||||
| CVE-2013-2194 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Multiple integer overflows in the Elf parser (libelf) in Xen 4.2.x and earlier allow local guest administrators with certain permissions to have an unspecified impact via a crafted kernel. | ||||
| CVE-2011-2901 | 2 Redhat, Xen | 3 Enterprise Linux, Rhel Eus, Xen | 2025-04-11 | N/A |
| Off-by-one error in the __addr_ok macro in Xen 3.3 and earlier allows local 64 bit PV guest administrators to cause a denial of service (host crash) via unspecified hypercalls that ignore virtual-address bits. | ||||
| CVE-2013-2078 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.0.2 through 4.0.4, 4.1.x, and 4.2.x allows local PV guest users to cause a denial of service (hypervisor crash) via certain bit combinations to the XSETBV instruction. | ||||
| CVE-2013-2077 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.0.x, 4.1.x, and 4.2.x does not properly restrict the contents of a XRSTOR, which allows local PV guest users to cause a denial of service (unhandled exception and hypervisor crash) via unspecified vectors. | ||||
| CVE-2013-0153 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
| The AMD IOMMU support in Xen 4.2.x, 4.1.x, 3.3, and other versions, when using AMD-Vi for PCI passthrough, uses the same interrupt remapping table for the host and all guests, which allows guests to cause a denial of service by injecting an interrupt into other guests. | ||||
| CVE-2013-2072 | 2 Debian, Xen | 2 Debian Linux, Xen | 2025-04-11 | N/A |
| Buffer overflow in the Python bindings for the xc_vcpu_setaffinity call in Xen 4.0.x, 4.1.x, and 4.2.x allows local administrators with permissions to configure VCPU affinity to cause a denial of service (memory corruption and xend toolstack crash) and possibly gain privileges via a crafted cpumap. | ||||
| CVE-2013-1964 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.0.x and 4.1.x incorrectly releases a grant reference when releasing a non-v1, non-transitive grant, which allows local guest administrators to cause a denial of service (host crash), obtain sensitive information, or possibly have other impacts via unspecified vectors. | ||||
| CVE-2013-1917 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 3.1 through 4.x, when running 64-bit hosts on Intel CPUs, does not clear the NT flag when using an IRET after a SYSENTER instruction, which allows PV guest users to cause a denial of service (hypervisor crash) by triggering a #GP fault, which is not properly handled by another IRET instruction. | ||||
| CVE-2013-1922 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| qemu-nbd in QEMU, as used in Xen 4.2.x, determines the format of a raw disk image based on the header, which allows local guest OS administrators to read arbitrary files on the host by modifying the header to identify a different format, which is used when the guest is restarted, a different vulnerability than CVE-2008-2004. | ||||
| CVE-2013-2076 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.0.x, 4.1.x, and 4.2.x, when running on AMD64 processors, only save/restore the FOP, FIP, and FDP x87 registers in FXSAVE/FXRSTOR when an exception is pending, which allows one domain to determine portions of the state of floating point instructions of other domains, which can be leveraged to obtain sensitive information such as cryptographic keys, a similar vulnerability to CVE-2006-1056. NOTE: this is the documented behavior of AMD64 processors, but it is inconsistent with Intel processors in a security-relevant fashion that was not addressed by the kernels. | ||||
| CVE-2013-1918 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Certain page table manipulation operations in Xen 4.1.x, 4.2.x, and earlier are not preemptible, which allows local PV kernels to cause a denial of service via vectors related to "deep page table traversal." | ||||
| CVE-2013-2211 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The libxenlight (libxl) toolstack library in Xen 4.0.x, 4.1.x, and 4.2.x uses weak permissions for xenstore keys for paravirtualised and emulated serial console devices, which allows local guest administrators to modify the xenstore value via unspecified vectors. | ||||
| CVE-2013-1442 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.0 through 4.3.x, when using AVX or LWP capable CPUs, does not properly clear previous data from registers when using an XSAVE or XRSTOR to extend the state components of a saved or restored vCPU after touching other restored extended registers, which allows local guest OSes to obtain sensitive information by reading the registers. | ||||
| CVE-2012-5511 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Stack-based buffer overflow in the dirty video RAM tracking functionality in Xen 3.4 through 4.1 allows local HVM guest OS administrators to cause a denial of service (crash) via a large bitmap image. | ||||
| CVE-2011-1763 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
| The get_free_port function in Xen allows local authenticated DomU users to cause a denial of service or possibly gain privileges via unspecified vectors involving a new event channel port. | ||||
| CVE-2013-1432 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.1.x and 4.2.x, when the XSA-45 patch is in place, does not properly maintain references on pages stored for deferred cleanup, which allows local PV guest kernels to cause a denial of service (premature page free and hypervisor crash) or possibly gain privileges via unspecified vectors. | ||||
| CVE-2013-1919 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.2.x and 4.1.x does not properly restrict access to IRQs, which allows local stub domain clients to gain access to IRQs and cause a denial of service via vectors related to "passed-through IRQs or PCI devices." | ||||
