|---|---|---|---|---|
| CVE-2016-1981 | 3 Debian, Qemu, Redhat | 3 Debian Linux, Qemu, Enterprise Linux | 2025-04-12 | 5.5 Medium |
| QEMU (aka Quick Emulator) built with the e1000 NIC emulation support is vulnerable to an infinite loop issue. It could occur while processing data via transmit or receive descriptors, provided the initial receive/transmit descriptor head (TDH/RDH) is set outside the allocated descriptor buffer. A privileged user inside guest could use this flaw to crash the QEMU instance resulting in DoS. | ||||

| CVE-2016-5107 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2025-04-12 | 6.0 Medium |
| The megasas_lookup_frame function in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, allows local guest OS administrators to cause a denial of service (out-of-bounds read and crash) via unspecified vectors. | ||||
| CVE-2012-6075 | 7 Canonical, Debian, Fedoraproject and 4 more | 15 Ubuntu Linux, Debian Linux, Fedora and 12 more | 2025-04-11 | N/A |
| Buffer overflow in the e1000_receive function in the e1000 device driver (hw/e1000.c) in QEMU 1.3.0-rc2 and other versions, when the SBP and LPE flags are disabled, allows remote attackers to cause a denial of service (guest OS crash) and possibly execute arbitrary guest code via a large packet. | ||||
| CVE-2013-4377 | 1 Qemu | 1 Qemu | 2025-04-11 | N/A |
| Use-after-free vulnerability in the virtio-pci implementation in Qemu 1.4.0 through 1.6.0 allows local users to cause a denial of service (daemon crash) by "hot-unplugging" a virtio device. | ||||
| 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-2011-1751 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2025-04-11 | N/A |
| The pciej_write function in hw/acpi_piix4.c in the PIIX4 Power Management emulation in qemu-kvm does not check if a device is hotpluggable before unplugging the PCI-ISA bridge, which allows privileged guest users to cause a denial of service (guest crash) and possibly execute arbitrary code by sending a crafted value to the 0xae08 (PCI_EJ_BASE) I/O port, which leads to a use-after-free related to "active qemu timers." | ||||
| CVE-2011-2527 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2025-04-11 | N/A |
| The change_process_uid function in os-posix.c in Qemu 0.14.0 and earlier does not properly drop group privileges when the -runas option is used, which allows local guest users to access restricted files on the host. | ||||
| CVE-2013-2007 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2025-04-11 | N/A |
| The qemu guest agent in Qemu 1.4.1 and earlier, as used by Xen, when started in daemon mode, uses weak permissions for certain files, which allows local users to read and write to these files. | ||||
| CVE-2013-4344 | 4 Canonical, Opensuse, Qemu and 1 more | 8 Ubuntu Linux, Opensuse, Qemu and 5 more | 2025-04-11 | N/A |
| Buffer overflow in the SCSI implementation in QEMU, as used in Xen, when a SCSI controller has more than 256 attached devices, allows local users to gain privileges via a small transfer buffer in a REPORT LUNS command. | ||||

| CVE-2010-0297 | 2 Qemu, Redhat | 3 Qemu, Enterprise Linux, Rhel Virtualization | 2025-04-11 | N/A |
| Buffer overflow in the usb_host_handle_control function in the USB passthrough handling implementation in usb-linux.c in QEMU before 0.11.1 allows guest OS users to cause a denial of service (guest OS crash or hang) or possibly execute arbitrary code on the host OS via a crafted USB packet. | ||||
