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-2012-2693 1 Redhat 4 Enterprise Linux, Libvirt, Rhel Virtualization and 1 more 2025-04-11 N/A
libvirt, possibly before 0.9.12, does not properly assign USB devices to virtual machines when multiple devices have the same vendor and product ID, which might cause the wrong device to be associated with a guest and might allow local users to access unintended USB devices.
CVE-2011-1146 1 Redhat 3 Enterprise Linux, Libvirt, Rhel Virtualization 2025-04-11 N/A
libvirt.c in the API in Red Hat libvirt 0.8.8 does not properly restrict operations in a read-only connection, which allows remote attackers to cause a denial of service (host OS crash) or possibly execute arbitrary code via a (1) virNodeDeviceDettach, (2) virNodeDeviceReset, (3) virDomainRevertToSnapshot, (4) virDomainSnapshotDelete, (5) virNodeDeviceReAttach, or (6) virConnectDomainXMLToNative call, a different vulnerability than CVE-2008-5086.
CVE-2010-0419 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 properly restrict writing of segment selectors to segment registers, which might allow 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.
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-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-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.
