CVE-2013-1797 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more 2025-04-11 N/A
Use-after-free vulnerability in arch/x86/kvm/x86.c in the Linux kernel through 3.8.4 allows guest OS users to cause a denial of service (host OS memory corruption) or possibly have unspecified other impact via a crafted application that triggers use of a guest physical address (GPA) in (1) movable or (2) removable memory during an MSR_KVM_SYSTEM_TIME kvm_set_msr_common operation.
CVE-2013-1798 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more 2025-04-11 N/A
The ioapic_read_indirect function in virt/kvm/ioapic.c in the Linux kernel through 3.8.4 does not properly handle a certain combination of invalid IOAPIC_REG_SELECT and IOAPIC_REG_WINDOW operations, which allows guest OS users to obtain sensitive information from host OS memory or cause a denial of service (host OS OOPS) via a crafted application.
CVE-2011-4622 1 Redhat 3 Enterprise Linux, Kvm, Rhel Virtualization 2025-04-11 N/A
The create_pit_timer function in arch/x86/kvm/i8254.c in KVM 83, and possibly other versions, does not properly handle when Programmable Interval Timer (PIT) interrupt requests (IRQs) when a virtual interrupt controller (irqchip) is not available, which allows local users to cause a denial of service (NULL pointer dereference) by starting a timer.
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-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-2011-2511 1 Redhat 3 Enterprise Linux, Libvirt, Rhel Virtualization 2025-04-11 N/A
Integer overflow in libvirt before 0.9.3 allows remote authenticated users to cause a denial of service (libvirtd crash) and possibly execute arbitrary code via a crafted VirDomainGetVcpus RPC call that triggers memory corruption.
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.
