CVE-2009-3722 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Rhel Virtualization 2026-04-23 N/A
The handle_dr function in arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 2.6.31.1 does not properly verify the Current Privilege Level (CPL) before accessing a debug register, which allows guest OS users to cause a denial of service (trap) on the host OS via a crafted application.
CVE-2009-0036 2 Libvirt, Redhat 2 Libvirt, Rhel Virtualization 2026-04-23 N/A
Buffer overflow in the proxyReadClientSocket function in proxy/libvirt_proxy.c in libvirt_proxy 0.5.1 might allow local users to gain privileges by sending a portion of the header of a virProxyPacket packet, and then sending the remainder of the packet with crafted values in the header, related to use of uninitialized memory in a validation check.
CVE-2009-3290 2 Linux, Redhat 2 Linux Kernel, Rhel Virtualization 2026-04-23 N/A
The kvm_emulate_hypercall function in arch/x86/kvm/x86.c in KVM in the Linux kernel 2.6.25-rc1, and other versions before 2.6.31, when running on x86 systems, does not prevent access to MMU hypercalls from ring 0, which allows local guest OS users to cause a denial of service (guest kernel crash) and read or write guest kernel memory via unspecified "random addresses."

CVE-2015-5279 2 Qemu, Redhat 4 Qemu, Enterprise Linux, Openstack and 1 more 2025-04-12 N/A
Heap-based buffer overflow in the ne2000_receive function in hw/net/ne2000.c in QEMU before 2.4.0.1 allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via vectors related to receiving packets.
CVE-2015-3209 8 Arista, Canonical, Debian and 5 more 20 Eos, Ubuntu Linux, Debian Linux and 17 more 2025-04-12 N/A
Heap-based buffer overflow in the PCNET controller in QEMU allows remote attackers to execute arbitrary code by sending a packet with TXSTATUS_STARTPACKET set and then a crafted packet with TXSTATUS_DEVICEOWNS set.
CVE-2014-3610 6 Canonical, Debian, Linux and 3 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2025-04-12 5.5 Medium
The WRMSR processing functionality in the KVM subsystem in the Linux kernel through 3.17.2 does not properly handle the writing of a non-canonical address to a model-specific register, which allows guest OS users to cause a denial of service (host OS crash) by leveraging guest OS privileges, related to the wrmsr_interception function in arch/x86/kvm/svm.c and the handle_wrmsr function in arch/x86/kvm/vmx.c.
CVE-2015-3456 3 Qemu, Redhat, Xen 7 Qemu, Enterprise Linux, Enterprise Virtualization and 4 more 2025-04-12 N/A
The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM.
CVE-2016-3710 7 Canonical, Citrix, Debian and 4 more 17 Ubuntu Linux, Xenserver, Debian Linux and 14 more 2025-04-12 8.8 High
The VGA module in QEMU improperly performs bounds checking on banked access to video memory, which allows local guest OS administrators to execute arbitrary code on the host by changing access modes after setting the bank register, aka the "Dark Portal" issue.
CVE-2014-3611 4 Canonical, Debian, Linux and 1 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2025-04-12 4.7 Medium
Race condition in the __kvm_migrate_pit_timer function in arch/x86/kvm/i8254.c in the KVM subsystem in the Linux kernel through 3.17.2 allows guest OS users to cause a denial of service (host OS crash) by leveraging incorrect PIT emulation.
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-2011-2511 1 Redhat 3 Enterprise Linux, Libvirt, Rhel Virtualization 2025-04-11 N/A
