| CVE-2010-0306 | 2 Kvm Qumranet, Redhat | 3 Kvm, Enterprise Linux, Rhel Virtualization | 2025-04-11 | N/A |
| The x86 emulator in KVM 83, when a guest is configured for Symmetric Multiprocessing (SMP), does not use the Current Privilege Level (CPL) and I/O Privilege Level (IOPL) to restrict instruction execution, which allows guest OS users to cause a denial of service (guest OS crash) or gain privileges on the guest OS by leveraging access to a (1) IO port or (2) MMIO region, and replacing an instruction in between emulator entry and instruction fetch, a related issue to CVE-2010-0298. | ||||
| CVE-2011-1486 | 1 Redhat | 3 Enterprise Linux, Libvirt, Rhel Virtualization | 2025-04-11 | N/A |
| libvirtd in libvirt before 0.9.0 does not use thread-safe error reporting, which allows remote attackers to cause a denial of service (crash) by causing multiple threads to report errors at the same time. | ||||
| CVE-2012-0029 | 2 Kvm Group, Redhat | 3 Qemu-kvm, Enterprise Linux, Rhel Virtualization | 2025-04-11 | N/A |
| Heap-based buffer overflow in the process_tx_desc function in the e1000 emulation (hw/e1000.c) in qemu-kvm 0.12, and possibly other versions, allows guest OS users to cause a denial of service (QEMU crash) and possibly execute arbitrary code via crafted legacy mode packets. | ||||
| CVE-2012-2121 | 2 Linux, Redhat | 3 Linux Kernel, Enterprise Linux, Rhel Virtualization | 2025-04-11 | N/A |
| The KVM implementation in the Linux kernel before 3.3.4 does not properly manage the relationships between memory slots and the iommu, which allows guest OS users to cause a denial of service (memory leak and host OS crash) by leveraging administrative access to the guest OS to conduct hotunplug and hotplug operations on devices. | ||||
| CVE-2012-3515 | 7 Canonical, Debian, Opensuse and 4 more | 15 Ubuntu Linux, Debian Linux, Opensuse and 12 more | 2025-04-11 | N/A |
| Qemu, as used in Xen 4.0, 4.1 and possibly other products, when emulating certain devices with a virtual console backend, allows local OS guest users to gain privileges via a crafted escape VT100 sequence that triggers the overwrite of a "device model's address space." | ||||
| CVE-2010-0429 | 1 Redhat | 4 Enterprise Linux, Enterprise Virtualization, Qspice and 1 more | 2025-04-11 | N/A |
| libspice, as used in QEMU-KVM in the Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2 and qspice 0.3.0, does not properly restrict the addresses upon which memory-management actions are performed, which allows guest OS users to cause a denial of service (guest OS crash) or possibly gain privileges via unspecified vectors. | ||||
| CVE-2017-2620 | 5 Citrix, Debian, Qemu and 2 more | 12 Xenserver, Debian Linux, Qemu and 9 more | 2024-11-21 | N/A |
| Quick emulator (QEMU) before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process. | ||||
| CVE-2017-2615 | 5 Citrix, Debian, Qemu and 2 more | 12 Xenserver, Debian Linux, Qemu and 9 more | 2024-11-21 | N/A |
| Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS or potentially execute arbitrary code on the host with privileges of QEMU process on the host. | ||||
