|---|---|---|---|---|
| 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-2011-2901 | 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-2012-2934 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-11 | N/A |
| Xen 4.0, and 4.1, when running a 64-bit PV guest on "older" AMD CPUs, does not properly protect against a certain AMD processor bug, which allows local guest OS users to cause a denial of service (host hang) via sequential execution of instructions across a non-canonical boundary, a different vulnerability than CVE-2012-0217. | ||||
| 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-2012-3433 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.0 and 4.1 allows local HVM guest OS kernels to cause a denial of service (domain 0 VCPU hang and kernel panic) by modifying the physical address space in a way that triggers excessive shared page search time during the p2m teardown. | ||||
| CVE-2012-3494 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-11 | N/A |
| The set_debugreg hypercall in include/asm-x86/debugreg.h in Xen 4.0, 4.1, and 4.2, and Citrix XenServer 6.0.2 and earlier, when running on x86-64 systems, allows local OS guest users to cause a denial of service (host crash) by writing to the reserved bits of the DR7 debug control register. | ||||
| 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." | ||||
| CVE-2012-6333 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Multiple HVM control operations in Xen 3.4 through 4.2 allow local HVM guest OS administrators to cause a denial of service (physical CPU consumption) via a large input. | ||||
| CVE-2014-1642 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The IRQ setup in Xen 4.2.x and 4.3.x, when using device passthrough and configured to support a large number of CPUs, frees certain memory that may still be intended for use, which allows local guest administrators to cause a denial of service (memory corruption and hypervisor crash) and possibly execute arbitrary code via vectors related to an out-of-memory error that triggers a (1) use-after-free or (2) double free. | ||||
| CVE-2012-3495 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-11 | N/A |
| The physdev_get_free_pirq hypercall in arch/x86/physdev.c in Xen 4.1.x and Citrix XenServer 6.0.2 and earlier uses the return value of the get_free_pirq function as an array index without checking that the return value indicates an error, which allows guest OS users to cause a denial of service (invalid memory write and host crash) and possibly gain privileges via unspecified vectors. | ||||
| CVE-2013-6400 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Xen 4.2.x and 4.3.x, when using Intel VT-d and a PCI device has been assigned, does not clear the flag that suppresses IOMMU TLB flushes when unspecified errors occur, which causes the TLB entries to not be flushed and allows local guest administrators to cause a denial of service (host crash) or gain privileges via unspecified vectors. | ||||
| CVE-2012-3432 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The handle_mmio function in arch/x86/hvm/io.c in the MMIO operations emulator for Xen 3.3 and 4.x, when running an HVM guest, does not properly reset certain state information between emulation cycles, which allows local guest OS users to cause a denial of service (guest OS crash) via unspecified operations on MMIO regions. | ||||
| 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. | ||||
| CVE-2012-3496 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-11 | N/A |
| XENMEM_populate_physmap in Xen 4.0, 4.1, and 4.2, and Citrix XenServer 6.0.2 and earlier, when translating paging mode is not used, allows local PV OS guest kernels to cause a denial of service (BUG triggered and host crash) via invalid flags such as MEMF_populate_on_demand. | ||||
| CVE-2007-6416 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-09 | N/A |
| The copy_to_user function in the PAL emulation functionality for Xen 3.1.2 and earlier, when running on ia64 systems, allows HVM guest users to access arbitrary physical memory by triggering certain mapping operations. | ||||
| CVE-2009-1758 | 3 Linux, Redhat, Xen | 3 Linux Kernel, Enterprise Linux, Xen | 2025-04-09 | N/A |
| The hypervisor_callback function in Xen, possibly before 3.4.0, as applied to the Linux kernel 2.6.30-rc4, 2.6.18, and probably other versions allows guest user applications to cause a denial of service (kernel oops) of the guest OS by triggering a segmentation fault in "certain address ranges." | ||||
| CVE-2008-3687 | 1 Xen | 2 Xen, Xen Flask Module | 2025-04-09 | N/A |
| Heap-based buffer overflow in the flask_security_label function in Xen 3.3, when compiled with the XSM:FLASK module, allows unprivileged domain users (domU) to execute arbitrary code via the flask_op hypercall. | ||||
| CVE-2009-3525 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-09 | N/A |
| The pyGrub boot loader in Xen 3.0.3, 3.3.0, and Xen-3.3.1 does not support the password option in grub.conf for para-virtualized guests, which allows attackers with access to the para-virtualized guest console to boot the guest or modify the guest's kernel boot parameters without providing the expected password. | ||||
| CVE-2007-1321 | 5 Debian, Fedoraproject, Qemu and 2 more | 6 Debian Linux, Fedora, Fedora Core and 3 more | 2025-04-09 | N/A |
| Integer signedness error in the NE2000 emulator in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to trigger a heap-based buffer overflow via certain register values that bypass sanity checks, aka QEMU NE2000 "receive" integer signedness error. NOTE: this identifier was inadvertently used by some sources to cover multiple issues that were labeled "NE2000 network driver and the socket code," but separate identifiers have been created for the individual vulnerabilities since there are sometimes different fixes; see CVE-2007-5729 and CVE-2007-5730. | ||||
| CVE-2007-1320 | 6 Debian, Fedoraproject, Opensuse and 3 more | 7 Debian Linux, Fedora, Fedora Core and 4 more | 2025-04-09 | N/A |
| Multiple heap-based buffer overflows in the cirrus_invalidate_region function in the Cirrus VGA extension in QEMU 0.8.2, as used in Xen and possibly other products, might allow local users to execute arbitrary code via unspecified vectors related to "attempting to mark non-existent regions as dirty," aka the "bitblt" heap overflow. | ||||
