| CVE-2013-1952 | 1 Xen | 1 Xen | 2025-04-11 | 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-2013-2076 | 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-2013-2212 | 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-2013-4329 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| The xenlight library (libxl) in Xen 4.0.x through 4.2.x, when IOMMU is disabled, provides access to a busmastering-capable PCI passthrough device before the IOMMU setup is complete, which allows local HVM guest domains to gain privileges or cause a denial of service via a DMA instruction. | ||||
| 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-2013-4494 | 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-2014-1950 | 1 Xen | 1 Xen | 2025-04-11 | N/A |
| Use-after-free vulnerability in the xc_cpupool_getinfo function in Xen 4.1.x through 4.3.x, when using a multithreaded toolstack, does not properly handle a failure by the xc_cpumap_alloc function, which allows local users with access to management functions to cause a denial of service (heap corruption) and possibly gain privileges via unspecified vectors. | ||||
| 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-2008-4993 | 2 Redhat, Xen | 2 Enterprise Linux, Xen | 2025-04-09 | 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-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. | ||||
| 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-2007-6416 | 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-2007-0998 | 2 Redhat, Xen | 3 Enterprise Linux, Fedora Core, Qemu | 2025-04-09 | 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-2007-5730 | 4 Debian, Qemu, Redhat and 1 more | 4 Debian Linux, Qemu, Enterprise Linux and 1 more | 2025-04-09 | 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-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-2009-1758 | 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-2023-20593 | 4 Amd, Debian, Redhat and 1 more | 147 Athlon Gold 7220u, Athlon Gold 7220u Firmware, Epyc 7232p and 144 more | 2025-02-13 | 5.5 Medium |
| An issue in “Zen 2” CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive information. | ||||
| CVE-2022-4949 | 2 Adsanityplugin, Xen | 2 Adsanity, Xen | 2025-02-13 | 8.8 High |
| The AdSanity plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'ajax_upload' function in versions up to, and including, 1.8.1. This makes it possible for authenticated attackers with Contributor+ level privileges to upload arbitrary files on the affected sites server which makes remote code execution possible. | ||||
| CVE-2022-42334 | 3 Debian, Fedoraproject, Xen | 3 Debian Linux, Fedora, Xen | 2025-02-13 | 6.5 Medium |
| x86/HVM pinned cache attributes mis-handling T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] To allow cachability control for HVM guests with passed through devices, an interface exists to explicitly override defaults which would otherwise be put in place. While not exposed to the affected guests themselves, the interface specifically exists for domains controlling such guests. This interface may therefore be used by not fully privileged entities, e.g. qemu running deprivileged in Dom0 or qemu running in a so called stub-domain. With this exposure it is an issue that - the number of the such controlled regions was unbounded (CVE-2022-42333), - installation and removal of such regions was not properly serialized (CVE-2022-42334). | ||||
