| CVE-2013-4554 | 1 Xen | 1 Xen | 2025-04-11 | 5.2 MEDIUM | 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-2012-4538 | 1 Xen | 1 Xen | 2025-04-11 | 4.9 MEDIUM | N/A |
| The HVMOP_pagetable_dying hypercall in Xen 4.0, 4.1, and 4.2 does not properly check the pagetable state when running on shadow pagetables, which allows a local HVM guest OS to cause a denial of service (hypervisor crash) via unspecified vectors. | |||||
| CVE-2012-6036 | 1 Xen | 1 Xen | 2025-04-11 | 4.4 MEDIUM | N/A |
| The (1) memc_save_get_next_page, (2) tmemc_restore_put_page and (3) tmemc_restore_flush_page functions in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 do not check for negative id pools, which allows local guest OS users to cause a denial of service (memory corruption and host crash) or possibly execute arbitrary code via unspecified vectors. 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-2012-3496 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-11 | 4.7 MEDIUM | 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-2013-6400 | 1 Xen | 1 Xen | 2025-04-11 | 6.8 MEDIUM | 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-2013-1952 | 1 Xen | 1 Xen | 2025-04-11 | 1.9 LOW | N/A |
| Xen 4.x, when using Intel VT-d for a bus mastering capable PCI device, does not properly check the source when accessing a bridge device's interrupt remapping table entries for MSI interrupts, which allows local guest domains to cause a denial of service (interrupt injection) via unspecified vectors. | |||||
| CVE-2013-1919 | 1 Xen | 1 Xen | 2025-04-11 | 4.7 MEDIUM | 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-2013-4551 | 1 Xen | 1 Xen | 2025-04-11 | 5.7 MEDIUM | N/A |
| Xen 4.2.x and 4.3.x, when nested virtualization is disabled, does not properly check the emulation paths for (1) VMLAUNCH and (2) VMRESUME, which allows local HVM guest users to cause a denial of service (host crash) via unspecified vectors related to "guest VMX instruction execution." | |||||
| CVE-2013-4368 | 1 Xen | 1 Xen | 2025-04-11 | 1.9 LOW | 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-2007-1320 | 5 Debian, Fedoraproject, Opensuse and 2 more | 6 Debian Linux, Fedora, Fedora Core and 3 more | 2025-04-09 | 7.2 HIGH | 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. | |||||
| CVE-2008-3687 | 1 Xen | 2 Xen, Xen Flask Module | 2025-04-09 | 6.8 MEDIUM | 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-2007-5730 | 3 Debian, Qemu, Xen | 3 Debian Linux, Qemu, Xen | 2025-04-09 | 7.2 HIGH | N/A |
| Heap-based buffer overflow in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to execute arbitrary code via crafted data in the "net socket listen" option, aka QEMU "net socket" heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of "NE2000 network driver and the socket code," but this is the correct identifier for the individual net socket listen vulnerability. | |||||
| CVE-2009-3525 | 1 Xen | 1 Xen | 2025-04-09 | 7.2 HIGH | 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-2008-4993 | 1 Xen | 1 Xen | 2025-04-09 | 6.9 MEDIUM | N/A |
| qemu-dm.debug in Xen 3.2.1 allows local users to overwrite arbitrary files via a symlink attack on the /tmp/args temporary file. | |||||
| CVE-2009-1758 | 2 Linux, Xen | 2 Linux Kernel, Xen | 2025-04-09 | 5.0 MEDIUM | 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-2007-6416 | 1 Xen | 1 Xen | 2025-04-09 | 4.6 MEDIUM | 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-2007-0998 | 2 Redhat, Xen | 3 Enterprise Linux, Fedora Core, Qemu | 2025-04-09 | 4.3 MEDIUM | N/A |
| The VNC server implementation in QEMU, as used by Xen and possibly other environments, allows local users of a guest operating system to read arbitrary files on the host operating system via unspecified vectors related to QEMU monitor mode, as demonstrated by mapping files to a CDROM device. NOTE: some of these details are obtained from third party information. | |||||
| CVE-2007-1321 | 4 Debian, Fedoraproject, Qemu and 1 more | 5 Debian Linux, Fedora, Fedora Core and 2 more | 2025-04-09 | 7.2 HIGH | 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-2023-46837 | 1 Xen | 1 Xen | 2025-02-13 | N/A | 3.3 LOW |
| Arm provides multiple helpers to clean & invalidate the cache for a given region. This is, for instance, used when allocating guest memory to ensure any writes (such as the ones during scrubbing) have reached memory before handing over the page to a guest. Unfortunately, the arithmetics in the helpers can overflow and would then result to skip the cache cleaning/invalidation. Therefore there is no guarantee when all the writes will reach the memory. This undefined behavior was meant to be addressed by XSA-437, but the approach was not sufficient. | |||||
| CVE-2023-34324 | 2 Linux, Xen | 2 Linux Kernel, Xen | 2025-02-13 | N/A | 4.9 MEDIUM |
| Closing of an event channel in the Linux kernel can result in a deadlock. This happens when the close is being performed in parallel to an unrelated Xen console action and the handling of a Xen console interrupt in an unprivileged guest. The closing of an event channel is e.g. triggered by removal of a paravirtual device on the other side. As this action will cause console messages to be issued on the other side quite often, the chance of triggering the deadlock is not neglectable. Note that 32-bit Arm-guests are not affected, as the 32-bit Linux kernel on Arm doesn't use queued-RW-locks, which are required to trigger the issue (on Arm32 a waiting writer doesn't block further readers to get the lock). | |||||
