CVE-2012-0218 1 Xen 1 Xen 2025-04-11 1.9 LOW 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-2013-6400 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-2012-3433 1 Xen 1 Xen 2025-04-11 4.9 MEDIUM 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-2013-1917 1 Xen 1 Xen 2025-04-11 1.9 LOW 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-2013-1432 1 Xen 1 Xen 2025-04-11 7.4 HIGH 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-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-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-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-2007-1321 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-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-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-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-2023-20593 3 Amd, Debian, Xen 140 Athlon Gold 7220u, Athlon Gold 7220u Firmware, Epyc 7232p and 137 more 2025-02-13 N/A 5.5 MEDIUM
An issue in “Zen 2” CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive information.
CVE-2022-42336 1 Xen 1 Xen 2025-01-22 N/A 3.3 LOW
Mishandling of guest SSBD selection on AMD hardware The current logic to set SSBD on AMD Family 17h and Hygon Family 18h processors requires that the setting of SSBD is coordinated at a core level, as the setting is shared between threads. Logic was introduced to keep track of how many threads require SSBD active in order to coordinate it, such logic relies on using a per-core counter of threads that have SSBD active. When running on the mentioned hardware, it's possible for a guest to under or overflow the thread counter, because each write to VIRT_SPEC_CTRL.SSBD by the guest gets propagated to the helper that does the per-core active accounting. Underflowing the counter causes the value to get saturated, and thus attempts for guests running on the same core to set SSBD won't have effect because the hypervisor assumes it's already active.
CVE-2023-4949 2 Gnu, Xen 2 Grub, Xen 2024-11-21 N/A 8.1 HIGH
An attacker with local access to a system (either through a disk or external drive) can present a modified XFS partition to grub-legacy in such a way to exploit a memory corruption in grub’s XFS file system implementation.
CVE-2023-34320 2 Arm, Xen 3 Cortex-a77, Cortex-a77 Firmware, Xen 2024-11-21 N/A 5.5 MEDIUM
Cortex-A77 cores (r0p0 and r1p0) are affected by erratum 1508412 where software, under certain circumstances, could deadlock a core due to the execution of either a load to device or non-cacheable memory, and either a store exclusive or register read of the Physical Address Register (PAR_EL1) in close proximity.
CVE-2023-20588 5 Amd, Debian, Fedoraproject and 2 more 78 Athlon Gold 3150g, Athlon Gold 3150g Firmware, Athlon Gold 3150ge and 75 more 2024-11-21 N/A 5.5 MEDIUM
A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality. 
CVE-2022-4949 2 Adsanityplugin, Xen 2 Adsanity, Xen 2024-11-21 N/A 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.
