| 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-2013-2077 | 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-2013-2078 | 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-2013-4553 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The XEN_DOMCTL_getmemlist hypercall in Xen 3.4.x through 4.3.x (possibly 4.3.1) does not always obtain the page_alloc_lock and mm_rwlock in the same order, which allows local guest administrators to cause a denial of service (host deadlock). | ||||
| 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-2013-2196 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Multiple unspecified vulnerabilities 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, related to "other problems" that are not CVE-2013-2194 or CVE-2013-2195. | ||||
| 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-2013-2212 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The vmx_set_uc_mode function in Xen 3.3 through 4.3, when disabling caches, allows local HVM guests with access to memory mapped I/O regions to cause a denial of service (CPU consumption and possibly hypervisor or guest kernel panic) via a crafted GFN range. | ||||
| CVE-2013-4355 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
| Xen 4.3.x and earlier does not properly handle certain errors, which allows local HVM guests to obtain hypervisor stack memory via a (1) port or (2) memory mapped I/O write or (3) other unspecified operations related to addresses without associated memory. | ||||
| CVE-2013-4368 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
| The outs instruction emulation in Xen 3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or GS: segment override, uses an uninitialized variable as a segment base, which allows local 64-bit PV guests to obtain sensitive information (hypervisor stack content) via unspecified vectors related to stale data in a segment register. | ||||
| CVE-2013-4370 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The ocaml binding for the xc_vcpu_getaffinity function in Xen 4.2.x and 4.3.x frees certain memory that may still be intended for use, which allows local users to cause a denial of service (heap corruption and crash) and possibly execute arbitrary code via unspecified vectors that trigger a (1) use-after-free or (2) double free. | ||||
| CVE-2013-4371 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Use-after-free vulnerability in the libxl_list_cpupool function in the libxl toolstack library in Xen 4.2.x and 4.3.x, when running "under memory pressure," returns the original pointer when the realloc function fails, which allows local users to cause a denial of service (heap corruption and crash) and possibly execute arbitrary code via unspecified vectors. | ||||
| CVE-2013-4416 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The Ocaml xenstored implementation (oxenstored) in Xen 4.1.x, 4.2.x, and 4.3.x allows local guest domains to cause a denial of service (domain shutdown) via a large message reply. | ||||
| CVE-2013-4494 | 3 Debian, Redhat, Xen | 3 Debian Linux, Enterprise Linux, Xen | 2025-04-11 | N/A |
| Xen before 4.1.x, 4.2.x, and 4.3.x does not take the page_alloc_lock and grant_table.lock in the same order, which allows local guest administrators with access to multiple vcpus to cause a denial of service (host deadlock) via unspecified vectors. | ||||
| CVE-2013-4554 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
| Xen 3.0.3 through 4.1.x (possibly 4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1) does not properly prevent access to hypercalls, which allows local guest users to gain privileges via a crafted application running in ring 1 or 2. | ||||
| CVE-2012-0218 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 3.4, 4.0, and 4.1, when the guest OS has not registered a handler for a syscall or sysenter instruction, does not properly clear a flag for exception injection when injecting a General Protection Fault, which allows local PV guest OS users to cause a denial of service (guest crash) by later triggering an exception that would normally be handled within Xen. | ||||
| 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-2011-2519 | 2 Redhat, Xen | 6 Enterprise Linux, Enterprise Linux Desktop, Enterprise Linux Server and 3 more | 2025-04-11 | N/A |
| Xen in the Linux kernel, when running a guest on a host without hardware assisted paging (HAP), allows guest users to cause a denial of service (invalid pointer dereference and hypervisor crash) via the SAHF instruction. | ||||
| CVE-2011-3131 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
| Xen 4.1.1 and earlier allows local guest OS kernels with control of a PCI[E] device to cause a denial of service (CPU consumption and host hang) via many crafted DMA requests that are denied by the IOMMU, which triggers a livelock. | ||||
| CVE-2012-3497 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| (1) TMEMC_SAVE_GET_CLIENT_WEIGHT, (2) TMEMC_SAVE_GET_CLIENT_CAP, (3) TMEMC_SAVE_GET_CLIENT_FLAGS and (4) TMEMC_SAVE_END 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 (NULL pointer dereference or memory corruption and host crash) or possibly have other unspecified impacts via a NULL client id. | ||||
